Builds on 28e626bde0 and f30d62c2fc. See the former for motivation.
Rows of the view show IO operations for a particular backend type, IO target
object, IO context combination (e.g. a client backend's operations on
permanent relations in shared buffers) and each column in the view is the
total number of IO Operations done (e.g. writes). So a cell in the view would
be, for example, the number of blocks of relation data written from shared
buffers by client backends since the last stats reset.
In anticipation of tracking WAL IO and non-block-oriented IO (such as
temporary file IO), the "op_bytes" column specifies the unit of the "reads",
"writes", and "extends" columns for a given row.
Rows for combinations of IO operation, backend type, target object and context
that never occur, are ommitted entirely. For example, checkpointer will never
operate on temporary relations.
Similarly, if an IO operation never occurs for such a combination, the IO
operation's cell will be null, to distinguish from 0 observed IO
operations. For example, bgwriter should not perform reads.
Note that some of the cells in the view are redundant with fields in
pg_stat_bgwriter (e.g. buffers_backend). For now, these have been kept for
backwards compatibility.

The motivation for this change is that when pg_dump dumps a
partitioned index that's marked REPLICA IDENTITY, it generates a
command sequence that applies REPLICA IDENTITY before the partitioned
index has been marked valid, causing restore to fail. We could
perhaps change pg_dump to not do it like that, but that would be
difficult and would not fix existing dump files with the problem.
There seems to be very little reason for the backend to disallow
this anyway --- the code ignores indisreplident when the index
isn't valid --- so instead let's fix it by allowing the case.
Commit 9511fb37a previously expressed a concern that allowing
indisreplident to be set on invalid indexes might allow us to
wind up in a situation where a table could have indisreplident
set on multiple indexes. I'm not sure I follow that concern
exactly, but in any case the only way that could happen is because
relation_mark_replica_identity is too trusting about the existing set
of markings being valid. Let's just rip out its early-exit code path
(which sure looks like premature optimization anyway; what are we
doing expending code to make redundant ALTER TABLE ... REPLICA
IDENTITY commands marginally faster and not-redundant ones marginally
slower?) and fix it to positively guarantee that no more than one
index is marked indisreplident.
The pg_dump failure can be demonstrated in all supported branches,
so back-patch all the way. I chose to back-patch 9511fb37a as well,
just to keep indisreplident handling the same in all branches.

Previously, CREATEROLE users were permitted to make nearly arbitrary
changes to roles that they didn't create, with certain exceptions,
particularly superuser roles. Instead, allow CREATEROLE users to make such
changes to roles for which they possess ADMIN OPTION, and to
grant membership only in roles for which they possess ADMIN OPTION.
When a CREATEROLE user who is not a superuser creates a role, grant
ADMIN OPTION on the newly-created role to the creator, so that they
can administer roles they create or for which they have been given
privileges.
With these changes, CREATEROLE users still have very significant
powers that unprivileged users do not receive: they can alter, rename,
drop, comment on, change the password for, and change security labels
on roles. However, they can now do these things only for roles for

This is not really complete, but it catches most cases of practical
interest. The main omissions are:
* regtype, regprocedure, and regoperator parse type names by
calling the main grammar, so any grammar-detected syntax error
will still be a hard error. Also, if one includes a type
modifier in such a type specification, errors detected by the
typmodin function will be hard errors.
* Lookup errors are handled just by passing missing_ok = true
to the relevant catalog lookup function. Because we've used
quite a restrictive definition of "missing_ok", this means that
edge cases such as "the named schema exists, but you lack
USAGE permission on it" are still hard errors.
It would make sense to me to replace most/all missing_ok
parameters with an escontext parameter and then allow these
additional lookup failure cases to be trapped too. But that's
a job for some other day.

get_call_result_type() is more expensive than the former style, but this

Because we added StaticAssertStmt() first before StaticAssertDecl(),
some uses as well as the instructions in c.h are now a bit backwards
from the "native" way static assertions are meant to be used in C.
This updates the guidance and moves some static assertions to better
places.
Specifically, since the addition of StaticAssertDecl(), we can put
static assertions at the file level. This moves a number of static
assertions out of function bodies, where they might have been stuck
out of necessity, to perhaps better places at the file level or in
header files.
Also, when the static assertion appears in a position where a
declaration is allowed, then using StaticAssertDecl() is more native
than StaticAssertStmt().

The parser included a set of checks coming from the files in charge of
holding the C functions used for the SQLValueFunction calls (as of
transformSQLValueFunction()), which are now moved within each function's
execution path, so this reduces the dependencies between the execution
and the parsing steps. As of this change, all the SQL keywords use the

This commit improves two code paths to open and close indexes a
minimum amount of times when doing a series of catalog updates or
inserts. CatalogTupleInsert() is costly when using it for multiple
inserts or updates compared to CatalogTupleInsertWithInfo(), as it would
need to open and close the indexes of the catalog worked each time an
operation is done.
This commit updates the following places:
- REINDEX CONCURRENTLY when copying statistics from one index relation
to the other. Multi-INSERTs are avoided here, as this would begin to
show benefits only for indexes with multiple expressions, for example,
which may not be the most common pattern. This change is noticeable in
profiles with indexes having many expressions, for example, and it would
improve any callers of CopyStatistics().
- Update of statistics on ANALYZE, that mixes inserts and updates.
In each case, the catalog indexes are opened only if at least one
insertion and/or update is required, to minimize the cost of the
operation. Like the previous coding, no indexes are opened as long as
at least one insert or update of pg_statistic has happened.

If a syntax error occurred in a SQL-language or PL/pgSQL-language
CREATE FUNCTION or DO command executed in a logical replication worker,
we'd suffer a null pointer dereference or assertion failure. That
seems like a rather contrived case, but nonetheless worth fixing.
The cause is that function_parse_error_transpose assumes it must be
executing within the context of a Portal, but logical/worker.c
doesn't create a Portal since it's not running the standard executor.
We can just back off the hard Assert check and make it fail gracefully
if there's not an ActivePortal. (I have a feeling that the aggressive
check here was my fault originally, probably because I wasn't sure if
the case would always hold and wanted to find out. Well, now we know.)

When creating a cast that uses a conversion function, we've
historically allowed the input and result types to be
binary-compatible with the function's input and result types,
rather than necessarily being identical. This means that the new
cast is logically dependent on the binary-compatible cast or casts
that it references: if those are defined by pg_cast entries, and you
try to restore the new cast without having defined them, it'll fail.
Hence, we should make pg_depend entries to record these dependencies
so that pg_dump knows that there is an ordering requirement.
This is not the only place where we allow such shortcuts; aggregate
functions for example are similarly lax, and in principle should gain
similar dependencies. However, for now it seems sufficient to fix
the cast-versus-cast case, as pg_dump's other ordering heuristics
should keep it out of trouble for other object types.
Per report from David Turoň; thanks also to Robert Haas for
preliminary investigation. I considered back-patching, but
seeing that this issue has existed for many years without
previous reports, it's not clear it's worth the trouble.
Moreover, back-patching wouldn't be enough to ensure that the
new pg_depend entries exist in existing databases anyway.

It can be useful to know when a relation has last been used, e.g., when
evaluating whether an index is still required. It was already possible to
infer the time of the last usage by tracking, e.g.,
pg_stat_all_indexes.idx_scan over time. But far from everybody does so.
To make it easier to detect the last time a relation has been scanned, track
that time in each relation's pgstat entry. To minimize overhead a) the
timestamp is updated only when the backend pending stats entry is flushed to
shared stats b) the last transaction's stop timestamp is used as the
timestamp.

There are a number of bugs in this area. Two of them are fixed here,
namely:
1. get_relation_idx_constraint_oid does not restrict the type of
constraint that's returned, so with sufficient bad luck it can
return the OID of a foreign key constraint. This has the effect that
a primary key in a partition can end up as a child of a foreign key,
which makes no sense (it needs to be the child of the equivalent
primary key.)
Change the API contract so that only index-backed constraints are
returned, mimicking get_constraint_index().
2. Both CloneFkReferenced and CloneFkReferencing clone a
self-referencing foreign key, so the partition ends up with
a duplicate foreign key. Change the former function to ignore such
constraints.
Add some tests to verify that things are better now. (However, these
new tests show some additional misbehavior that will be fixed later --
namely that there's a constraint marked NOT VALID.)

There are still some alignment-related failures in the buildfarm,

just realized that it increased the size of many WAL records by 4 bytes
because a block reference contains a RelFileLocator. The effect of that
hasn't been studied or discussed, so revert for now.
RelFileNumbers are now assigned using a separate counter, instead of
being assigned from the OID counter. This counter never wraps around:
if all 2^56 possible RelFileNumbers are used, an internal error
occurs. As the cluster is limited to 2^64 total bytes of WAL, this
limitation should not cause a problem in practice.
If the counter were 64 bits wide rather than 56 bits wide, we would
need to increase the width of the BufferTag, which might adversely
impact buffer lookup performance. Also, this lets us use bigint for
pg_class.relfilenode and other places where these values are exposed
at the SQL level without worrying about overflow.
This should remove the need to keep "tombstone" files around until
the next checkpoint when relations are removed. We do that to keep
RelFileNumbers from being recycled, but now that won't happen
anyway. However, this patch doesn't actually change anything in
this area; it just makes it possible for a future patch to do so.

Because index creation does not go through heap_create_with_catalog() we
didn't call pgstat_create_relation(), leading to index stats of a newly
created realtion not getting dropped during rollback. To fix, move the
pgstat_create_relation() to heap_create(), which indexes do use.
Similarly, because dropping an index does not go through
heap_drop_with_catalog(), we didn't drop index stats when the transaction
dropping an index committed. Here there's no convenient common path for
indexes and relations, so index_drop() now calls pgstat_drop_relation().

Backpatch: 15-, like 8b1dccd37c, which introduced the bug
We previously thought that allowing such cases can confuse users when they
specify DROP TABLES IN SCHEMA but that doesn't seem to be the case based
on discussion. This helps to uplift the restriction during
ALTER TABLE ... SET SCHEMA which used to ensure that we couldn't end up
with a publication having both a schema and the same schema's table.
To allow this, we need to forbid having any schema on a publication if
column lists on a table are specified (and vice versa). This is because
otherwise we still need a restriction during ALTER TABLE ... SET SCHEMA to
forbid cases where it could lead to a publication having both a schema and

this clause no longer a perfect parallel of the GRANT variant "ALL
