release docs:  mention PL/pgSQL as supporting event triggers in PG 9.3
Remove unused regression test files.

euc_* and mule_internal test cases were identical to the ones in
src/test/mb. sql_ascii didn't exist elsewhere, but has been broken since
2001, and doesn't seem very interesting anyway. drop.sql hasn't been used
since 2000, when regress.sh was removed.
Remove single space on end of a line in xlog.c

Emit msg correctly for timeline-crossing crash
Init crash recovery using the latest available TLI

This simplifies the handling of crashes after fast promotion and various
minor cases that can exist in short timing windows around that case.

Broad fix to bug reported by Michael Paquier on -hackers,
approach prompted by Heikki Linnakangas
Clarify documentation of EXPLAIN (TIMING OFF) option.

Clarify that this option doesn't suppress measurement of the statement's
total runtime.

Greg Smith
Fix escaping in generated recovery.conf file.

In the primary_conninfo line that "pg_basebackup -R" generates, single
quotes in parameter values need to be escaped into \\'; the libpq parser
requires the quotes to be escaped into \', and recovery.conf parser requires
the \ to be escaped into \\.

Also, don't quote parameter values unnecessarily, to make the connection
string prettier. Most options in a libpq connection string don't need
quoting.

Reported by Hari Babu, closer analysis by Zoltan Boszormenyi, although I
didn't use his patch.
Documentation spell checking and markup improvements
9.3 release docs: fix DROP TABLE IF EXISTS
Patch from Joe Abbate.
9.3 release notes:  fix SGML markup for DROP TABLE IF EXISTS
Maintain ThisTimeLineID correctly in checkpointer

checkpointer needs to reset ThisTimeLineID after
a restartpoint to allow installing/recycling new
WAL files. If recovery has already ended this
would leave ThisTimeLineID set incorrectly and
so we must reset it otherwise later checkpoints
do not have the correct timeline.

Bug report by Heikki Linnakangas.
Further investigation by Heikki and myself.
After fast promotion use CHECKPOINT_FORCE

Not necessary for correctness, just to make
log_checkpoints output look less singular.

9.3 release notes:  improve cached plan mention
Per suggestion from Tom Lane.
Print line number correctly in COPY.

When COPY uses the multi-insert method to insert a batch of tuples into the
heap at a time, incorrect line number was printed if something went wrong in
inserting the index tuples (primary key failure, for exampl), or processing
after row triggers.

Fixes bug #8173 reported by Lloyd Albin. Backpatch to 9.2, where the multi-
insert code was added.
Fix typo in comment.

Pavan Deolasee
Remove pageinspect--1.0.sql

We're not installing it anymore.

Documentation fix for ALTER TYPE .. RENAME

The documentation for ALTER TYPE .. RENAME claimed to support a
RESTRICT/CASCADE option at the 'type' level, which wasn't implemented
and doesn't make a whole lot of sense to begin with.  What is supported,
and previously undocumented, is

ALTER TYPE .. RENAME ATTRIBUTE .. RESTRICT/CASCADE.

I've updated the documentation and back-patched this to 9.1 where it was
first introduced.
pg_upgrade docs:  mention need to set parameters for vacuumdb.
Document auto_explain.log_timing.

pgindent run for release 9.3
This is the first run of the Perl-based pgindent script.  Also update
pgindent instructions.
