c1f91a38e2 Fix rewrite code so that rules are in fact executed in order by name,
rather than being reordered according to INSTEAD attribute for
implementation convenience.
Also, increase compiled-in recursion depth limit from 10 to 100 rewrite
cycles.  10 seems pretty marginal for situations where multiple rules
exist for the same query.  There was a complaint about this recently,
so I'm going to bump it up.  (Perhaps we should make the limit a GUC
parameter, but that's too close to being a new feature to do in beta.)

necessarily done the same way.

8fc1f413f4 - Link the entries in the table to the catalog heading
- Wrap them in the <database class="table"> tags, since thats what they
are (no markup rules for this, so it inherits from parent -- no style
change)
- Mention that pg_database, pg_shadow, and pg_group are global, and the
rest are local to the specific DB. (I believe this is correct).

Attached is a patch to fix the mb linking problems on AIX. As a nice side effect

it reduces the duplicate symbol warnings to linking libpq.so and libecpg.so
(all shlibs that are not postmaster loadable modules).

Please apply to current (only affects AIX).

The _LARGE_FILES problem is unfortunately still open, unless Peter
has fixed it per his recent idea.

909a8377db The valid return value should be MODIFY instead of MODIFIED.
The error message said so :-)

In 25.3. Using PL/Python

        If the trigger "when" is BEFORE, you may return None or "OK"
        from the Python function to indicate the tuple is unmodified, "SKIP"
        to abort the event, or "MODIFIED" to indicate you've modified the tuple.

9946b83ded Bring SIMILAR TO and SUBSTRING into some semblance of conformance with
the SQL99 standard.  (I'm not sure that the character-class features are
quite right, but that can be fixed later.)  Document SQL99 and POSIX
regexps as being different features; provide variants of SUBSTRING for
each.

eb3adab568 Provide an upgrade strategy for dump files containing functions declared
with OPAQUE.  CREATE LANGUAGE, CREATE TRIGGER, and CREATE TYPE will all
accept references to functions declared with OPAQUE --- but they will
issue a NOTICE, and will modify the function entries in pg_proc to have
the preferred type-safe argument or result types instead of OPAQUE.
Per recent pghackers discussions.

674818dce8 This patch corrects a minor mis-statement in the CREATE DOMAIN docs,
pointed out by Chris KL on -hackers a little while ago -- NOT NULL !=
CHECK xxx IS NOT NULL.
