handled as special productions. This is needed to keep us honest about
user-schema type names that happen to coincide with system type names.
Per pghackers discussion 24-Apr. To avoid bloating the keyword list
too much, I removed the translations for datetime, timespan, and lztext,
all of which were slated for destruction several versions back anyway.
in gram.y can make use of the keywords.c string table, instead of having
their own copies of the keyword strings. This saves a few kilobytes and
more importantly eliminates an opportunity for cut-and-paste errors.
in parse error messages, not just the part scanned by the last flex rule.
For example,
select "foo" "bar";
used to draw
ERROR: parser: parse error at or near """
which was rather unhelpful. Now it gives
ERROR: parser: parse error at or near ""bar""
Also, error messages concerning bitstring literals and suchlike will
quote the source text at you, not the processed internal form of the literal.
lists to join RTEs, attach a list of Vars and COALESCE expressions that will
replace the join's alias variables during planning. This simplifies
flatten_join_alias_vars while still making it easy to fix up varno references
when transforming the query tree. Add regression test cases for interactions
of subqueries with outer joins.
pg_database, pg_shadow, pg_group, all of which now have potentially-long
fields. Along the way, get rid of SharedSystemRelationNames list: shared
rels are now identified in their include/pg_catalog/*.h files by a
BKI_SHARED_RELATION macro, while indexes and toast rels inherit sharedness
automatically from their parent table. Fix some bugs with failure to detoast
pg_group.grolist during ALTER GROUP.
messages more uniform and internationalizable: the global array
aclcheck_error_strings[] is gone in favor of a subroutine
aclcheck_error(). Partial implementation of namespace-related
permission checks --- not all done yet.
divide backend/commands by object type, let's try to pay at least
minimal attention to respecting that structure, eh? Also reorder the
contents of tablecmds.c; it seems odd to me to put ALTER commands before
creation/deletion commands.
per pghackers discussion. Add some more typsanity tests, and clean
up some problems exposed thereby (broken or missing array types for
some built-in types). Also, clean up loose ends from unknownin/out
patch.

1) Wrong translations of embedded escape sequences inside outer join escape
sequences.
2) Wrong translation of parameter markers inside outer joins and function
escape sequences.
3) Bad concatenation of date, time, timestamp constants with next word in
