Fix markup errors from recent patch.
1. In keeping with the recent discussion that there should be more
said about views, stored procedures, and triggers, in the tutorial, I
have added a bit of verbiage to that end.
2. Some formatting changes to the datetime discussion, as well as
addition of a citation of a relevant book on calendars.

Use the new GUC variable default_with_oids in pg_dump, rather than using

Upgrade ALTER TABLE DROP COLUMN so that it can drop an OID column, and
remove separate implementation of ALTER TABLE SET WITHOUT OIDS in favor
of doing a regular DROP. Also, cause CREATE TABLE to account completely
correctly for the inheritance status of the OID column. This fixes
problems with dropping OID columns that have dependencies, as noted by
Christopher Kings-Lynne, as well as making sure that you can't drop an
OID column that was inherited from a parent.

Rewrite pg_dump's comment-dumping code to pull over all the comments
in one query, rather than making a separate query for each object that

third.

During btree index build, sort equal-keyed tuples according to their
TID (heap position). This doesn't do anything to the validity of the

with multiple evaluations of a volatile 'val', and it allows the CASE
expression to be reverse-listed in its original form by ruleutils.c.

Replace the switching function ExecEvalExpr() with a macro that jumps
directly to the appropriate per-node execution function, using a function
pointer stored by ExecInitExpr. This speeds things up by eliminating one
level of function call. The function-pointer technique also enables further
small improvements such as only making one-time tests once (and then
changing the function pointer). Overall this seems to gain about 10%
on evaluation of simple expressions, which isn't earthshaking but seems
a worthwhile gain for a relatively small hack. Per recent discussion
on pghackers.

Windows uses codepages rather than the environment, so we work around
