pghackers proposal of 8-Nov. All the existing cross-type comparison
operators (int2/int4/int8 and float4/float8) have appropriate support.
The original proposal of storing the right-hand-side datatype as part of
the primary key for pg_amop and pg_amproc got modified a bit in the event;
it is easier to store zero as the 'default' case and only store a nonzero
when the operator is actually cross-type. Along the way, remove the
long-since-defunct bigbox_ops operator class.
Remove the 'strategy map' code, which was a large amount of mechanism
that no longer had any use except reverse-mapping from procedure OID to
strategy number. Passing the strategy number to the index AM in the
first place is simpler and faster.
This is a preliminary step in planned support for cross-datatype index
operations. I'm committing it now since the ScanKeyEntryInitialize()
API change touches quite a lot of files, and I want to commit those
changes before the tree drifts under me.
regression=# select 1 from tenk1 ta cross join tenk1 tb for update;
ERROR: no relation entry for relid 3
7.3 said "SELECT FOR UPDATE cannot be applied to a join", which was better
but still wrong, considering that 7.2 took the query just fine. Fix by
making transformForUpdate() ignore JOIN and other special RTE types,
rather than trying to mark them FOR UPDATE. The actual error message now
only appears if you explicitly name the join in FOR UPDATE.
process the command as though it were issued by the object owner.
This prevents creating weird scenarios in which the same privileges
may appear to flow from different sources, and ensures that a superuser
can in fact revoke all privileges if he wants to. In particular this
means that the regression tests work when run by a superuser other than
the original bootstrap userid. Per report from Larry Rosenman.
behavior of malloc and realloc when request size is 0. Fix escape
sequence recognizer so that only valid 3-digit octal sequences are
treated as escape sequences ... isdigit() is not a correct test.
rule split the query into one INSERT and one UPDATE where the UPDATE
then hit's the just created row without modifying the key fields again.
In this special case, the new key slipped in totally unchecked.

offered for completion only when the input-so-far is at least 'pg_'.
This seems to be the best compromise behavior emerging from yesterday's
discussion. While at it, refactor code to eliminate repetitive use of
nearly identical queries, which was exceedingly tedious to maintain.
Also const-ify code more thoroughly in hopes of moving constant data into
text segment, and remove unnecessary length limit on queries.
ACL array, and force languages to be treated as owned by the bootstrap
user ID. (pg_language should have a lanowner column, but until it does
this will have to do as a workaround.)
"schema." has been typed. This allows readline to complete subsequent
characters immediately if all relations in the target schema start with
the same prefix. This actually worked before, but I unintentionally
broke it a few days ago.
Also, make completion schema-aware for GRANT, REVOKE, VACUUM.
Make a LOT of fixes to syscat.source to:
* Set search_path properly (and reset it)
* Add schema name to all results
* Add schema name to ORDER BY first
* Make checks for user-defined objects match reality
* format_type all type names
* Respect attisdropped
* Change !~ to 'not like' since it's more standard

0.0/0.0. That option appears to affect the regression test result as well.
The compiler documentation doesn't recommend -O4 for universal use, so
let's stick to the conservative -O (== -O2) by default.
subquery that didn't previously have one. We have traditionally made
the caller of ResolveNew responsible for updating the hasSubLinks flag
of the outermost query, but this fails to account for hasSubLinks in
subqueries. Fix ResolveNew to handle this. We might later want to
change the calling convention of ResolveNew so that it can fix the
outer query too, simplifying callers. But I went with the localized
fix for now. Per bug report from J Smith, 20-Oct-03.
to ensure any needed compiler support routines are included. This is
arguably appropriate on *every* gcc platform, but for the moment I'll take
the conservative approach of only doing it on a platform where it's
provably useful. Per complaint from Heiko Lehmann, 13-Feb-03, as well
as personal experience --- contrib/pgstattuple has never worked for me,
but it does now.
fully search-path-proof yet; also, element_types view did not work for
parameters and result types of functions, because it didn't generate
the object_name for the function the same way the data_type_privileges
view does. While at it, centralize dependencies on INDEX_MAX_KEYS/
FUNC_MAX_ARGS into a function returning setof int, so that it will be
easier to fix information_schema for nonstandard values of these
parameters.
Use pg_get_constraintdef instead of pg_constraint.consrc
Use UNION ALL instread of UNION
Make use of regclass type for getting OID of system catalogs
Add schema qualifications where necessary
Fix typos
