Fix comment.c to not depend on parser token values, per discussion awhile
back.

scans that will most likely be caused by SearchSysCache probes.  Also,
share some code between index deletion and table deletion.

varno of index's relation is not 1.  This embarrassing oversight pointed
out by Dmitry Tkach 12-Jul-02.

pg_relcheck is gone; CHECK, UNIQUE, PRIMARY KEY, and FOREIGN KEY
constraints all have real live entries in pg_constraint.  pg_depend
exists, and RESTRICT/CASCADE options work on most kinds of DROP;
however, pg_depend is not yet very well populated with dependencies.
(Most of the ones that are present at this point just replace formerly
hardwired associations, such as the implicit drop of a relation's pg_type
entry when the relation is dropped.)  Need to add more logic to create
dependency entries, improve pg_dump to dump constraints in place of
indexes and triggers, and add some regression tests.

It used to return them as a,b in one row, and now returns
a in one row, and b in one row

2) Change default build mode to multibyte(Windows).

as discussed on hackers.

This is the first cut toward CREATE CONVERSION/DROP CONVERSION implementaion.
The commands can now add/remove tuples to the new pg_conversion system
catalog, but that's all. Still need work to make them actually working.
Documentations, regression tests also need work.

are managed as per request.

Moved from merging with table attributes to applying themselves during
coerce_type() and coerce_type_typmod.

Regression tests altered to test the cast() scenarios.

fixed bug reported by Michael, Dietrich (mdt@emdete.de) where a large object handle was being used after the end of the transaction and thus resulting in an error.

Now includes the following new fields:
 integer/float date/time storage
 maximum length of names (+1; they must also include a null termination)
 maximum number of function arguments
 maximum length of locale name
