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
