> 	o -SELECT col FROM tab WHERE numeric_col = 10.1 fails, requires quotes

pointed out by Barry Lind: UPDATE bigintcol = 10000000000 fails because
the constant is initially taken as float8.  We really need a better way,
but it's not gonna happen for 7.3.

Also, remove int4reltime() function, which is redundant with the
existing binary-compatibility coercion path from int4 to reltime,
and probably has been unreachable code for a long while.

type for runtime constraint checks, instead of misusing the parse-time
Constraint node for the purpose.  Fix some damage introduced into type
coercion logic; in particular ensure that a coerced expression tree will
read out the correct result type when inspected (patch had broken some
RelabelType cases).  Enforce domain NOT NULL constraints against columns
that are omitted from an INSERT.

you try to use the tupdesc to build a tuple.

pg_locks view to show transaction ID locks separately from ordinary
relation locks.  Avoid showing N duplicate rows when the same lock is
held multiple times (seems unlikely that users care about exact hold
count).  Improve documentation.

plpgsql RETURN NEXT to verify that returned values match the expected
tupdesc.

to false provides more SQL-spec-compliant behavior than we had before.
I am not sure that setting it false is actually a good idea yet; there
is a lot of client-side code that will probably be broken by turning
autocommit off.  But it's a start.

Loosely based on a patch by David Van Wie.

get out of sync with its parent.  Patch by Alvaro Herrera, with some

Improve wording of pre-7.3 syntax mention.

is needed on later versions.

than hard-wiring it to PL/pgSQL.

I've attached a patch which should fix these problems.

diffs to 7.3-devel and may not be applicable to 7.2. I have included a
change covered by a previous bugfix patch I submitted (the problem with
-.1 not being accepted by cube_in). It does not include a fix for the
potential buffer overrun issue I reported for cube_yyerror in
cubeparse.y.
