Move test modules from contrib to src/test/modules This is advance preparation for introducing even more test modules; the easy solution is to add them to contrib, but that's bloated enough that it seems a good time to think of something different. Moved modules are dummy_seclabel, test_shm_mq, test_parser and worker_spi. (test_decoding was also a candidate, but there was too much opposition to moving that one. We can always reconsider later.)

Re-add BRIN isolation test This time, instead of using a core isolation test, put it on its own test module; this way it can require the pageinspect module to be present before running. The module's Makefile is loosely modeled after test_decoding's, so that it's easy to add further tests for either pg_regress or isolationtester later. Backpatch to 9.5.

Keep track of transaction commit timestamps Transactions can now set their commit timestamp directly as they commit, or an external transaction commit timestamp can be fed from an outside system using the new function TransactionTreeSetCommitTsData(). This data is crash-safe, and truncated at Xid freeze point, same as pg_clog. This module is disabled by default because it causes a performance hit, but can be enabled in postgresql.conf requiring only a server restart. A new test in src/test/modules is included. Catalog version bumped due to the new subdirectory within PGDATA and a couple of new SQL functions.

Support testing of cases where table schemas change after planning. We have various cases where we allow DDL on tables to be performed with less than full AccessExclusiveLock. This requires concurrent queries to be able to cope with the DDL change mid-flight, but up to now we had no repeatable way to test such cases. To improve that, invent a test module that allows halting a backend after planning and then resuming execution once we've done desired actions in another session. (The same approach could be used to inject delays in other places, if there's a suitable hook available.) This commit includes a single test case, which is meant to exercise the previously-untestable ExecCreatePartitionPruneState code repaired by commit 7a980dfc6. We'd probably not bother with this if that were the only foreseen benefit, but I expect additional test cases will use this infrastructure in the future.

Implement pipeline mode in libpq Pipeline mode in libpq lets an application avoid the Sync messages in the FE/BE protocol that are implicit in the old libpq API after each query. The application can then insert Sync at its leisure with a new libpq function PQpipelineSync. This can lead to substantial reductions in query latency.

Add PL/Sample to src/test/modules/ PL/Sample is an example template of procedural-language handler. This can be used as a base to implement a custom PL, or as a facility to test APIs dedicated to PLs. Much more could be done in this module, like adding a simple validator, but this is left as future work. The documentation included originally some C code to understand the basics of PL handler implementation, but it was outdated, and not really helpful either if trying to implement a new procedural language, particularly when it came to the integration of a PL installation with CREATE EXTENSION.

Fix confusion in SP-GiST between attribute type and leaf storage type. According to the documentation, the attType passed to the opclass config function (and also relied on by the core code) is the type of the heap column or expression being indexed. But what was actually being passed was the type stored for the index column. This made no difference for user-defined SP-GiST opclasses, because we weren't allowing the STORAGE clause of CREATE OPCLASS to be used, so the two types would be the same. But it's silly not to allow that, seeing that the built-in poly_ops opclass has a different value for opckeytype than opcintype, and that if you want to do lossy storage then the types must really be different. (Thus, user-defined opclasses doing lossy storage had to lie about what type is in the index.) Hence, remove the restriction, and make sure that we use the input column type not opckeytype where relevant. For reasons of backwards compatibility with existing user-defined opclasses, we can't quite insist that the specified leafType match the STORAGE clause; instead just add an amvalidate() warning if they don't match. Also fix some bugs that would only manifest when trying to return index entries when attType is different from attLeafType. It's not too surprising that these have not been reported, because the only usual reason for such a difference is to store the leaf value lossily, rendering index-only scans impossible. Add a src/test/modules module to exercise cases where attType is different from attLeafType and yet index-only scan is supported. Discussion: https://postgr.es/m/3728741.1617381471@sss.pgh.pa.us

Add Bloom filter implementation. A Bloom filter is a space-efficient, probabilistic data structure that can be used to test set membership. Callers will sometimes incur false positives, but never false negatives. The rate of false positives is a function of the total number of elements and the amount of memory available for the Bloom filter. Two classic applications of Bloom filters are cache filtering, and data synchronization testing. Any user of Bloom filters must accept the possibility of false positives as a cost worth paying for the benefit in space efficiency. This commit adds a test harness extension module, test_bloomfilter. It can be used to get a sense of how the Bloom filter implementation performs under varying conditions. This is infrastructure for the upcoming "heapallindexed" amcheck patch, which verifies the consistency of a heap relation against one of its indexes.

Add support for COPY TO callback functions This is useful as a way for extensions to process COPY TO rows in the way they see fit (say auditing, analytics, backend, etc.) without the need to invoke an external process running as the OS user running the backend through PROGRAM that requires superuser rights. COPY FROM already provides a similar callback for logical replication. For COPY TO, the callback is triggered when we are ready to send a row in CopySendEndOfRow(), which is the same code path as when sending a row to a frontend or a pipe/file. A small test module, test_copy_callbacks, is added to provide some coverage for this facility.

Allow on-the-fly capture of DDL event details This feature lets user code inspect and take action on DDL events. Whenever a ddl_command_end event trigger is installed, DDL actions executed are saved to a list which can be inspected during execution of a function attached to ddl_command_end. The set-returning function pg_event_trigger_ddl_commands can be used to list actions so captured; it returns data about the type of command executed, as well as the affected object. This is sufficient for many uses of this feature. For the cases where it is not, we also provide a "command" column of a new pseudo-type pg_ddl_command, which is a pointer to a C structure that can be accessed by C code. The struct contains all the info necessary to completely inspect and even reconstruct the executed command. There is no actual deparse code here; that's expected to come later. What we have is enough infrastructure that the deparsing can be done in an external extension. The intention is that we will add some deparsing code in a later release, as an in-core extension. A new test module is included. It's probably insufficient as is, but it should be sufficient as a starting point for a more complete and future-proof approach.

Fix overflow check and comment in GIN posting list encoding. The comment did not match what the code actually did for integers with the 43rd bit set. You get an integer like that, if you have a posting list with two adjacent TIDs that are more than 2^31 blocks apart. According to the comment, we would store that in 6 bytes, with no continuation bit on the 6th byte, but in reality, the code encodes it using 7 bytes, with a continuation bit on the 6th byte as normal. The decoding routine also handled these 7-byte integers correctly, except for an overflow check that assumed that one integer needs at most 6 bytes. Fix the overflow check, and fix the comment to match what the code actually does. Also fix the comment that claimed that there are 17 unused bits in the 64-bit representation of an item pointer. In reality, there are 64-32-11=21. Fitting any item pointer into max 6 bytes was an important property when this was written, because in the old pre-9.4 format, item pointers were stored as plain arrays, with 6 bytes for every item pointer. The maximum of 6 bytes per integer in the new format guaranteed that we could convert any page from the old format to the new format after upgrade, so that the new format was never larger than the old format. But we hardly need to worry about that anymore, and running into that problem during upgrade, where an item pointer is expanded from 6 to 7 bytes such that the data doesn't fit on a page anymore, is implausible in practice anyway. Backpatch to all supported versions. This also includes a little test module to test these large distances between item pointers, without requiring a 16 TB table. It is not backpatched, I'm including it more for the benefit of future development of new posting list formats.

Add IntegerSet, to hold large sets of 64-bit ints efficiently. The set is implemented as a B-tree, with a compact representation at leaf items, using Simple-8b algorithm, so that clusters of nearby values use less memory.

This includes a unit test module, in src/test/modules/test_integerset.

Avoid using INFO elevel for what are fundamentally debug messages. Commit 6f6b99d13 stuck an INFO message into the fast path for checking partition constraints, for no very good reason except that it made it easy for the regression tests to verify that that path was taken. Assorted later patches did likewise, increasing the unsuppressable-chatter level from ALTER TABLE even more. This isn't good for the user experience, so let's drop these messages down to DEBUG1 where they belong. So as not to have a loss of test coverage, create a TAP test that runs the relevant queries with client_min_messages = DEBUG1 and greps for the expected messages. This testing method is a bit brute-force --- in particular, it duplicates the execution of a fair amount of the core create_table and alter_table tests. We experimented with other solutions, but running any significant amount of standard testing with client_min_messages = DEBUG1 seems to have a lot of output-stability pitfalls, cf commits bbb96c370 and 5655565c0. Possibly at some point we'll look into whether we can reduce the amount of test duplication. Backpatch into v12, because some of these messages are new in v12 and we don't really want to ship it that way.

While this test suite covers a fair bit of ground (67% of pg_dump.c and quite a bit of the other files in src/bin/pg_dump), there is still quite a bit which remains to be added to provide better code coverage. Still, this is quite a bit better than we had, and has found a few bugs already (note that the CREATE TRANSFORM test is commented out, as it is currently failing).

Add test scaffolding for exercising optimizer's predicate-proof logic. The predicate-proof code in predtest.c is a bit hard to test as-is: you have to construct a query whose plan changes depending on the success of a test, and in tests that have been around for awhile, it's always possible that the plan shape is now being determined by some other factor. Our existing regression tests aren't doing real well at providing full code coverage of predtest.c, either. So, let's add a small test module that allows directly inspecting the results of predicate_implied_by() and predicate_refuted_by() for arbitrary boolean expressions. I chose the set of tests committed here in order to get reasonably complete code coverage of predtest.c just from running this test module, and to cover some cases called out as being interesting in the existing comments. We might want to add more later. But this set already shows a few cases where perhaps things could be improved. Indeed, this exercise proves that predicate_refuted_by() is buggy for the case of clause_is_check = true, though fortunately we aren't using that case anywhere yet. I'll look into doing something about that in a separate commit. For now, just memorialize the current behavior. Discussion: https://postgr.es/m/5983.1520487191@sss.pgh.pa.us

Add a test module for the regular expression package. This module provides a function test_regex() that is functionally rather like regexp_matches(), but with additional debugging-oriented options and additional output. The debug options are somewhat obscure; they are chosen to match the API of the test harness that Henry Spencer wrote way-back-when for use in Tcl. With this, we can import all the test cases that Spencer wrote originally, even for regex functionality that we don't currently expose in Postgres. This seems necessary because we can no longer rely on Tcl to act as upstream and verify any fixes or improvements that we make. In addition to Spencer's tests, I added a few for lookbehind constraints (which we added in 2015, and Tcl still hasn't absorbed) that are modeled on his tests for lookahead constraints. After looking at code coverage reports, I also threw in a couple of tests to more fully exercise our "high colormap" logic. According to my testing, this brings the check-world coverage for src/backend/regex/ from 71.1% to 86.7% of lines.

Make ResourceOwners more easily extensible. Instead of having a separate array/hash for each resource kind, use a single array and hash to hold all kinds of resources. This makes it possible to introduce new resource "kinds" without having to modify the ResourceOwnerData struct. In particular, this makes it possible for extensions to register custom resource kinds. The old approach was to have a small array of resources of each kind, and if it fills up, switch to a hash table. The new approach also uses an array and a hash, but now the array and the hash are used at the same time. The array is used to hold the recently added resources, and when it fills up, they are moved to the hash. This keeps the access to recent entries fast, even when there are a lot of long-held resources. All the resource-specific ResourceOwnerEnlarge*(), ResourceOwnerRemember*(), and ResourceOwnerForget*() functions have been replaced with three generic functions that take resource kind as argument. For convenience, we still define resource-specific wrapper macros around the generic functions with the old names, but they are now defined in the source files that use those resource kinds. The release callback no longer needs to call ResourceOwnerForget on the resource being released. ResourceOwnerRelease unregisters the resource from the owner before calling the callback. That needed some changes in bufmgr.c and some other files, where releasing the resources previously always called ResourceOwnerForget. Each resource kind specifies a release priority, and ResourceOwnerReleaseAll releases the resources in priority order. To make that possible, we have to restrict what you can do between phases. After calling ResourceOwnerRelease(), you are no longer allowed to remember any more resources in it or to forget any previously remembered resources by calling ResourceOwnerForget. There was one case where that was done previously. At subtransaction commit, AtEOSubXact_Inval() would handle the invalidation messages and call RelationFlushRelation(), which temporarily increased the reference count on the relation being flushed. We now switch to the parent subtransaction's resource owner before calling AtEOSubXact_Inval(), so that there is a valid ResourceOwner to temporarily hold that relcache reference. Other end-of-xact routines make similar calls to AtEOXact_Inval() between release phases, but I didn't see any regression test failures from those, so I'm not sure if they could reach a codepath that needs remembering extra resources. There were two exceptions to how the resource leak WARNINGs on commit were printed previously: llvmjit silently released the context without printing the warning, and a leaked buffer io triggered a PANIC. Now everything prints a WARNING, including those cases. Add tests in src/test/modules/test_resowner.

RLS fixes, new hooks, and new test module In prepend_row_security_policies(), defaultDeny was always true, so if there were any hook policies, the RLS policies on the table would just get discarded. Fixed to start off with defaultDeny as false and then properly set later if we detect that only the default deny policy exists for the internal policies. The infinite recursion detection in fireRIRrules() didn't properly manage the activeRIRs list in the case of WCOs, so it would incorrectly report infinite recusion if the same relation with RLS appeared more than once in the rtable, for example "UPDATE t ... FROM t ...". Further, the RLS expansion code in fireRIRrules() was handling RLS in the main loop through the rtable, which lead to RTEs being visited twice if they contained sublink subqueries, which prepend_row_security_policies() attempted to handle by exiting early if the RTE already had securityQuals. That doesn't work, however, since if the query involved a security barrier view on top of a table with RLS, the RTE would already have securityQuals (from the view) by the time fireRIRrules() was invoked, and so the table's RLS policies would be ignored. This is fixed in fireRIRrules() by handling RLS in a separate loop at the end, after dealing with any other sublink subqueries, thus ensuring that each RTE is only visited once for RLS expansion. The inheritance planner code didn't correctly handle non-target relations with RLS, which would get turned into subqueries during planning. Thus an update of the form "UPDATE t1 ... FROM t2 ..." where t1 has inheritance and t2 has RLS quals would fail. Fix by making sure to copy in and update the securityQuals when they exist for non-target relations. process_policies() was adding WCOs to non-target relations, which is unnecessary, and could lead to a lot of wasted time in the rewriter and the planner. Fix by only adding WCO policies when working on the result relation. Also in process_policies, we should be copying the USING policies to the WITH CHECK policies on a per-policy basis, fix by moving the copying up into the per-policy loop. Lastly, as noted by Dean, we were simply adding policies returned by the hook provided to the list of quals being AND'd, meaning that they would actually restrict records returned and there was no option to have internal policies and hook-based policies work together permissively (as all internal policies currently work). Instead, explicitly add support for both permissive and restrictive policies by having a hook for each and combining the results appropriately. To ensure this is all done correctly, add a new test module (test_rls_hooks) to test the various combinations of internal, permissive, and restrictive hook policies. Largely from Dean Rasheed (thanks!): CAEZATCVmFUfUOwwhnBTcgi6AquyjQ0-1fyKd0T3xBWJvn+xsFA@mail.gmail.com Author: Dean Rasheed, though I added the new hooks and test module.

Move test modules from contrib to src/test/modules This is advance preparation for introducing even more test modules; the easy solution is to add them to contrib, but that's bloated enough that it seems a good time to think of something different. Moved modules are dummy_seclabel, test_shm_mq, test_parser and worker_spi. (test_decoding was also a candidate, but there was too much opposition to moving that one. We can always reconsider later.)

Add test module for SLRUs This commit introduces a basic facility to test SLRUs, in terms of initialization, page reads, writes, flushes, truncation and deletions, using SQL wrappers around the APIs of slru.c. This should be easily extensible at will, and it can be used as a starting point for someone willing to implement an external module that makes use of SLRUs (LWLock tranche registering and SLRU initialization particularly). As this requires a loaded library, the tests use a custom configuration file and are disabled under installcheck.

Move rolenames test out of the core regression tests. This test script is unsafe to run in "make installcheck" mode for (at least) two reasons: it creates and destroys some role names that don't follow the "regress_xxx" naming convention, and it sets and then resets the application_name GUC attached to every existing role. While we've not had complaints, these surely are not good things to do within a production installation, and regress.sgml pretty clearly implies that we won't do them. Rather than lose test coverage altogether, let's just move this script somewhere where it will get run by "make check" but not "make installcheck". src/test/modules/ already has that property. Since it seems likely that we'll want other regression tests in future that also exceed the constraints of "make installcheck", create a generically-named src/test/modules/unsafe_tests/ directory to hold them.

Allow on-the-fly capture of DDL event details This feature lets user code inspect and take action on DDL events. Whenever a ddl_command_end event trigger is installed, DDL actions executed are saved to a list which can be inspected during execution of a function attached to ddl_command_end. The set-returning function pg_event_trigger_ddl_commands can be used to list actions so captured; it returns data about the type of command executed, as well as the affected object. This is sufficient for many uses of this feature. For the cases where it is not, we also provide a "command" column of a new pseudo-type pg_ddl_command, which is a pointer to a C structure that can be accessed by C code. The struct contains all the info necessary to completely inspect and even reconstruct the executed command. There is no actual deparse code here; that's expected to come later. What we have is enough infrastructure that the deparsing can be done in an external extension. The intention is that we will add some deparsing code in a later release, as an in-core extension. A new test module is included. It's probably insufficient as is, but it should be sufficient as a starting point for a more complete and future-proof approach.

Introduce --with-ssl={openssl} as a configure option This is a replacement for the existing --with-openssl, extending the logic to make easier the addition of new SSL libraries. The grammar is chosen to be similar to --with-uuid, where multiple values can be chosen, with "openssl" as the only supported value for now. The original switch, --with-openssl, is kept for compatibility.
