Support "OR condition ..." in plpgsql EXCEPTION clauses to make the syntax
more nearly Oracle-equivalent. Allow matching by category as well as
specific error code. Document the set of available condition names

that a SPI function call error is reported.

Still another try at matching system timezone nicely. On non-Windows
machines, break tie scores by preferring shorter zone names over longer;
for names of equal length, prefer the alphabetically first name. This
yields for example 'EST5EDT' not 'America/New_York' for US eastern time.
On Windows, abandon the whole concept of inspecting the detailed behavior
of the system TZ library, because it doesn't bear inspection :-(. Instead
use a hardwired mapping table to select our zone name based on the
result of strftime %Z output. Windows code from Magnus Hagander.

There are still some things that need refinement; in particular I fear
that the recognized set of error condition names probably has little in

Restructure error handling as recently discussed. It is now really
possible to trap an error inside a function rather than letting it
propagate out to PostgresMain. You still have to use AbortCurrentTransaction

Fix oversight: in case where SIGTERM is received while there are
live backends, the archiver and stats processes never got sent a
kill signal. They'd eventually exit on their own, but not for awhile,

file on a platform that doesn't allow removal of busy executables.
Also, tweak main loop logic so that we will perform the background

Here is another patch that fixes a stack of pg_dump bugs:
* Fix help text ordering
* Add back --set-session-authorization to pg_dumpall. Updated the docs
for that. Updated help for that.
* Dump ALTER USER commands for the cluster owner ("pgsql"). These are
dumped AFTER the create user and create database commands in case the
permissions to do these have been revoked.
* Dump ALTER OWNER for public schema (because it's possible to change
it). This was done by adding TOC entries for the public schema, and
filtering them out at archiver time. I also save the owner in the TOC
entry just for the public schema.
* Suppress dumping single quotes around schema_path and DateStyle
options when they are set using ALTER USER or ALTER DATABASE. Added a
comment to the steps in guc.c to remind people to update that list.
* Fix dumping in --clean mode against a pre-7.3 server. It just sets
all drop statements to assume the public schema, allowing it to restore
without error.
* Cleaned up text output. eg. Don't output -- Tablespaces comment if
there are none. Same for groups and users.
* Make the commands to DELETE FROM pg_shadow and DELETE FROM pg_group
only be output when -c mode is enabled. I'm not sure why that hasn't
been done before?!?!
This should be good for application asap, after which I will start on
regression dumping 7.0-7.4 databases.
