Tom Lane f31dc0ada7 Partial indexes work again, courtesy of Martijn van Oosterhout.
Note: I didn't force an initdb, figuring that one today was enough.
However, there is a new function in pg_proc.h, and pg_dump won't be
able to dump partial indexes until you add that function.

Tom Lane 4d58a7ca87 Optimizer can now estimate selectivity of IS NULL, IS NOT NULL,
IS TRUE, etc, with some degree of verisimilitude.  Split out
selectivity support functions from builtins.h into a new header
file selfuncs.h, so as to reduce the number of header files builtins.h
must depend on.  Fix a few missing inclusions exposed thereby.
From Joe Conway, with some kibitzing from Tom Lane.

Tom Lane c9499e68da has_table_privilege functions from Joe Conway (with some kibitzing from
Tom Lane).  For the moment, only the OID/name variants are provided.
I didn't force initdb, but the additions to the 'privileges' regress
test won't pass until you do one.

Bruce Momjian d4a4d4c326 Attached is a patch adding following functions:
inet(text), cidr(text): convert a text value into inet/cidr
set_masklen(inet): set masklen on the inet value

Patch also contains regression checks for these functions.

Bruce Momjian 76e9ad1f55 Back out has_table_privilege patch. 2001-06-12 16:34:27 +00:00
Bruce Momjian 58c909bb8d OK -- here's take #5.
It "make"s and "make check"s clean against current cvs tip.

There are now both Text and Name variants, and the regression test support
is rolled into the patch. Note that to be complete wrt Name based variants,
there are now 12 user visible versions of has_table_privilege:

has_table_privilege(Text usename, Text relname, Text priv_type)
has_table_privilege(Text usename, Name relname, Text priv_type)
has_table_privilege(Name usename, Text relname, Text priv_type)
has_table_privilege(Name usename, Name relname, Text priv_type)
has_table_privilege(Text relname, Text priv_type) /* assumes current_user */
has_table_privilege(Name relname, Text priv_type) /* assumes current_user */
has_table_privilege(Text usename, Oid reloid, Text priv_type)
has_table_privilege(Name usename, Oid reloid, Text priv_type)
has_table_privilege(Oid reloid, Text priv_type)  /* assumes current_user */
has_table_privilege(Oid usesysid, Text relname, Text priv_type)
has_table_privilege(Oid usesysid, Name relname, Text priv_type)
has_table_privilege(Oid usesysid, Oid reloid, Text priv_type)

For the Text based inputs, a new internal function, get_Name is used
(shamelessly copied from get_seq_name in sequence.c) to downcase if not
quoted, or remove quotes if quoted, and truncate. I also added a few test
cases for the downcasing, quote removal, and Name based variants to the
regression test.

Tom Lane 4a66f9dd54 Change scoping of table and join refnames to conform to SQL92: a JOIN
clause with an alias is a <subquery> and therefore hides table references
appearing within it, according to the spec.  This is the same as the
preliminary patch I posted to pgsql-patches yesterday, plus some really
grotty code in ruleutils.c to reverse-list a query tree with the correct
alias name depending on context.  I'd rather not have done that, but unless
we want to force another initdb for 7.1, there's no other way for now.

Bruce Momjian 623bf843d2 Change Copyright from PostgreSQL, Inc to PostgreSQL Global Development Group. 2001-01-24 19:43:33 +00:00
Tom Lane 61784c54b5 Change default output formatting for CIDR to be unabbreviated, per
recommendation from Paul Vixie.  Add a new abbrev() function to produce
abbreviated format as text.  No forced initdb, but new function is not
available unless you do an initdb or add the pg_proc row manually.
2000-12-22 18:00:24 +00:00
Tom Lane 376784cf8a Repair erroneous use of hashvarlena() for MACADDR, which is not a
varlena type.  (I did not force initdb, but you won't see the fix
unless you do one.)  Also, make sure all index support operators and
functions are careful not to leak memory for toasted inputs; I had
missed some hash and rtree support ops on this point before.

Tom Lane bbea3643a3 Store current LC_COLLATE and LC_CTYPE settings in pg_control during initdb;
re-adopt these settings at every postmaster or standalone-backend startup.
This should fix problems with indexes becoming corrupt due to failure to
provide consistent locale environment for postmaster at all times.  Also,
refuse to start up a non-locale-enabled compilation in a database originally
initdb'd with a non-C locale.  Suppress LIKE index optimization if locale
is not "C" or "POSIX" (are there any other locales where it's safe?).
Issue NOTICE during initdb if selected locale disables LIKE optimization.

Tom Lane 93fcbd140a Make oidin/oidout produce and consume unsigned representation of Oid,
rather than just being aliases for int4in/int4out.  Give type Oid a
full set of comparison operators that do proper unsigned comparison,
instead of reusing the int4 comparators.  Since pg_dump is now doing
unsigned comparisons of OIDs, it is now *necessary* that we play by
the rules here.  In fact, given that btoidcmp() has been doing unsigned
comparison for quite some time, it seems likely that we have index-
corruption problems in 7.0 and before once the Oid counter goes past
2G.  Fixing these operators is a necessary step before we can think
about 8-byte Oid, too.

Tom Lane a210023008 Adjust INET/CIDR display conventions and reimplement some INET/CIDR
functions, per recent discussions on pghackers.  For now, I have called
the verbose-display formatting function text(), but will reconsider if
enough people object.
initdb forced.

Peter Eisentraut b0c1c53a43 Integer binary operators, from Marko Kreen <marko@l-t.ee>. Renamed bitxor
operator to '#' for consistency.  Parser still needs work.

Peter Eisentraut 457ac0331c Implement differentiation between CURRENT_USER and SESSION_USER as per SQL.
There is still no effective difference but it will kick in once setuid
functions exist (not included here).  Make old getpgusername() alias for
current_user.
2000-09-19 18:18:04 +00:00
Tom Lane 8ae9ad1cb8 Reimplement LIKE/ESCAPE as operators so that indexscan optimization
can still work, per recent discussion on pghackers.  Correct some bugs
in ILIKE implementation.

Jan Wieck daf1e3a702 Added functions
quote_ident(text) returns text
    quote_literal(text) returns text

These are handy to build up properly quoted query strings
for the new PL/pgSQL EXECUTE functionality to submit
dynamic DDL statements.

Tom Lane 3d3ca010aa Avoid creating a TOAST table if we can prove that the maximum tuple
length is < TOAST_TUPLE_THRESHOLD, even with toastable column types
present.  For example, CREATE TABLE foo (f1 int, f2 varchar(100))
does not require a toast table, even though varchar is a toastable
type.

Tom Lane 782c16c6a1 SQL-language functions are now callable in ordinary fmgr contexts ...
for example, an SQL function can be used in a functional index.  (I make
no promises about speed, but it'll work ;-).)  Clean up and simplify
handling of functions returning sets.

Thomas G. Lockhart 8a35cbe1db Add functions to convert to and from text, and to truncate to MAC OUI.
Remove hardcoded macaddr_manuf(), which had really old, obsolete info.
 Replace this with some contrib/mac/ code to maniag OUI info from IEEE.
2000-08-23 06:04:49 +00:00
Thomas G. Lockhart 371a485dba Include the case-insensitive LIKE prototypes. 2000-08-07 01:43:35 +00:00
Thomas G. Lockhart 30ab107dbf Implement LIKE/ESCAPE. Change parser to use like()/notlike()
rather than the "~~" operator; this made it easy to add ESCAPE features.
Implement ILIKE, NOT ILIKE, and the ESCAPE clause for them.
 afaict this is not MultiByte clean, but lots of other stuff isn't either.
Fix up underlying support code for LIKE/NOT LIKE.
 Things should be faster and does not require internal string copying.
Update regression test to add explicit checks for
 LIKE/NOT LIKE/ILIKE/NOT ILIKE.
Remove colon and semi-colon operators as threatened in 7.0.
Implement SQL99 COMMIT/AND NO CHAIN.
 Throw elog(ERROR) on COMMIT/AND CHAIN per spec
 since we don't yet support it.
Implement SQL99 CREATE/DROP SCHEMA as equivalent to CREATE DATABASE.
 This is only a stopgap or demo since schemas will have another
 implementation soon.
Remove a few unused production rules to get rid of warnings
 which crept in on the last commit.
Fix up tabbing in some places by removing embedded spaces.

Tom Lane ed9ca68758 Convert inet-related functions to new fmgr style. I have also taken it
on myself to do something about the non-self-consistency of the inet
comparison functions.  The results are probably still semantically wrong
(inet and cidr should have different comparison semantics, I think)
but at least the boolean operators now agree with each other and with
the sort order of indexes on inet/cidr.
2000-08-03 23:07:51 +00:00
Tom Lane c298d74d49 More functions updated to new fmgr style --- money, name, tid datatypes.
We're reaching the mopup stage here (good thing too, this is getting
tedious).
2000-08-03 16:35:08 +00:00
Tom Lane 463f1f5cda Convert all remaining float4 and float8 functions to new fmgr style.
At this point I think it'd be possible to make float4 be pass-by-value
without too much work --- and float8 too on machines where Datum is
8 bytes.  Something to try when the mood strikes, anyway.
2000-08-01 18:29:35 +00:00
Tom Lane 8f9fa0e143 Type lztext is toast.
(Sorry, couldn't help it...)

Removed type filename as well, since it's unused and probably useless.
INITDB FORCED, because pg_rewrite columns are now plain text again.
2000-07-30 22:14:09 +00:00
Tom Lane d70d46fd60 PATH and POLYGON datatypes are now TOASTable. Associated functions
updated to new fmgr style.  Deleted hoary old functions for compatibility
with pre-6.1 representations of these datatypes.
2000-07-29 18:46:12 +00:00
Tom Lane 1ebe1da296 bpchar, varchar, bytea, numeric are toastable --- if you initdb, which
I did not force.  I marked numeric as compressable-but-not-move-off-able,
partly to test that storage mode and partly because I've got doubts
that numerics are large enough to need external storage.
2000-07-29 03:26:51 +00:00
Tom Lane bec98a31c5 Revise aggregate functions per earlier discussions in pghackers.
There's now only one transition value and transition function.
NULL handling in aggregates is a lot cleaner.  Also, use Numeric
accumulators instead of integer accumulators for sum/avg on integer
datatypes --- this avoids overflow at the cost of being a little slower.
Implement VARIANCE() and STDDEV() aggregates in the standard backend.

Also, enable new LIKE selectivity estimators by default.  Unrelated
change, but as long as I had to force initdb anyway...

Tom Lane ba62fe32c3 Remove long-dead support for invoking queries from dynamically loaded
backend functions via backend PQexec().  The SPI interface has long
been our only documented way to do this, and the backend pqexec/portal
code is unused and suffering bit-rot.  I'm putting it out of its misery.
2000-07-08 03:04:41 +00:00
Peter Eisentraut de85dd1d51 - format_type function, in use by psql
- added bigint as synonym of int8
- set typelem of varlen non-array types to 0
2000-07-07 19:24:43 +00:00
Tom Lane 8ecac94bb2 Functions on 'text' type updated to new fmgr style. 'text' is
now TOAST-able.
2000-07-06 05:48:31 +00:00
Tom Lane 40f64064ff Update textin() and textout() to new fmgr style. This is just phase
one of updating the whole text datatype, but there are so dang many
calls of these two routines that it seems worth a separate commit.
2000-07-05 23:12:09 +00:00
Tom Lane c590273fef Clean up bogosities in pg_opclass, pg_amop, pg_amproc. There are amproc
entries now for int8 and network hash indexes.  int24_ops and int42_ops
are gone.  pg_opclass no longer contains multiple entries claiming to be
the default opclass for the same datatype.  opr_sanity regress test
extended to catch errors like these in the future.

Tom Lane f2d1205322 Another batch of fmgr updates. I think I have gotten all old-style
functions that take pass-by-value datatypes.  Should be ready for
port testing ...
2000-06-13 07:35:40 +00:00
Tom Lane ae526b4070 Another round of updates for new fmgr, mostly in the datetime code. 2000-06-09 01:11:16 +00:00
Bruce Momjian 20ad43b576 Mark functions as static and ifdef NOT_USED as appropriate. 2000-06-08 22:38:00 +00:00
Tom Lane 48165ec226 Latest round of fmgr updates. All functions with bool,char, or int2
inputs have been converted to newstyle.  This should go a long way towards
fixing our portability problems with platforms where char and short
parameters are passed differently from int-width parameters.  Still
more to do for the Alpha port however.
2000-06-05 07:29:25 +00:00
Tom Lane 18952f6744 Second round of fmgr changes: triggers are now invoked in new style,
CurrentTriggerData is history.
2000-05-29 01:59:17 +00:00
Tom Lane 82849df6c6 Add new selectivity estimation functions for pattern-matching operators
(LIKE and regexp matches).  These are not yet referenced in pg_operator,
so by default the system will continue to use eqsel/neqsel.
Also, tweak convert_to_scalar() logic so that common prefixes of strings
are stripped off, allowing better accuracy when all strings in a table
share a common prefix.
2000-04-16 04:41:03 +00:00
