The Problem: Occassionally a DBA needs to dump a database to a new
encoding. In instances where the current encoding, (or lack of an
encoding, like SQL_ASCII) is poorly supported on the target database
server, it can be useful to dump into a particular encoding. But,
currently the only way to set the encoding of a pg_dump file is to
change client_encoding in postgresql.conf and restart postmaster.
This is more than a little awkward for production systems.

into pg_catalog rather than public, and supports dumping languages whose
handlers are found there. This will make it easier to drop the public
schema if desired.
Unlike the previous patch, the comments have been updated and I have
reformatted some code to meet Alvarro's request to stick to 80 cols. (I
actually aghree with this - it makes printing the code much nicer).
I think I did the right thing w.r.t versions earlier than 7.3, but I
have no real way of checking, so that should be checked by someone with
more/older knowledge than me ;-)

inspection of shared catalogs. This allows pg_dumpall to continue to
work with pre-8.1 servers that likely won't have a database named postgres.
Also, suppress output of SYSID options for users and groups, since server
no longer does anything with these except emit a rude message.
There is much more to be done to update pg_dumpall for the roles feature,
but this at least makes it usable again. Per gripe from Chris K-L.
have adequate mechanisms for tracking the contents of databases and
tablespaces). This solves the longstanding problem that you can drop a
user who still owns objects and/or has access permissions.

find myself typing a command and then wanting to get the syntax for it.
So I do a ctrl-a and add a \h: but psql does not recognize the command,
because I have stuff attached to it (e.g. "alter table foobar"), so I
have to scroll over and delete everything except the name of the command
itself. This patch gives \h three chances to match: if nothing matches
the complete string (current behavior), it tries to match the first two
words (e.g. "ALTER TABLE"). If that fails, it tries to match the first
word (e.g. "DELETE").

chdir into PGDATA and subsequently use relative paths instead of absolute
paths to access all files under PGDATA. This seems to give a small
performance improvement, and it should make the system more robust
against naive DBAs doing things like moving a database directory that
has a live postmaster in it. Per recent discussion.
and pg_auth_members. There are still many loose ends to finish in this
patch (no documentation, no regression tests, no pg_dump support for
instance). But I'm going to commit it now anyway so that Alvaro can
make some progress on shared dependencies. The catalog changes should
be pretty much done.
name matches the name of any parent-table constraint, without looking
at the constraint text. This is a not-very-bulletproof workaround for
the problem exhibited by Berend Tober last month. We really ought to
record constraint inheritance status in pg_constraint, but it's looking
like that may not get done for 8.1 --- and even if it does, we will
need this kluge for dumping from older servers.

Add GUC variables:
"escape_string_warning" - warn about backslashes in non-E strings
"escape_string_syntax" - supports E'' syntax?
"standard_compliant_strings" - treats backslashes literally in ''
Update code to use E'' when escapes are used.
in the database. The old behavior (reindex system catalogs only) is now
available as REINDEX SYSTEM. I did not add the complementary REINDEX USER
case since there did not seem to be consensus for this, but it would be
trivial to add later. Per recent discussions.
(1) The code doesn't initialize `sum', so the initial "does the checksum
match?" test is wrong.
(2) The loop that is intended to check for a "null block" just checks
the first byte of the tar block 512 times, rather than each of the
512 bytes one time (!), which I'm guessing was the intent.
It was only through sheer luck that this worked in the first place.

using the recently added lo_create() function. The restore logic in
pg_restore is greatly simplified as well, since there's no need anymore
to try to adjust database references to match a new set of blob OIDs.
unlike template0 and template1 does not have any special status in
terms of backend functionality. However, all external utilities such
as createuser and createdb now connect to "postgres" instead of
template1, and the documentation is changed to encourage people to use
"postgres" instead of template1 as a play area. This should fix some
longstanding gotchas involving unexpected propagation of database
objects by createdb (when you used template1 without understanding
the implications), as well as ameliorating the problem that CREATE
DATABASE is unhappy if anyone else is connected to template1.

pghackers discussions.

history customizable through a variable named HISTFILE, analogous to
psql's already implemented HISTCONTROL and HISTSIZE variables, and
bash's HISTFILE-Variable.
The motivation was to be able to get psql to maintain separate
histories for separate databases. This is now easily achievable
through a line like the following in ~/.psqlrc:
\set HISTFILE ~/.psql_history-:DBNAME

psql. i.e. "\pset format troff-ms". The patch also corrects some
problems with the "latex" format, notably defining an extra column in
the output table, and correcting some alignment issues; it also
changes the output to match the border setting as documented in the
manual page and as shown with the "aligned" format.
The troff-ms output is mostly identical to the latex output allowing
for the differences between the two typesetters.
The output should be saved in a file and piped as follows:
cat file | tbl | troff -T ps -ms > file.ps
or
tbl file | troff -T ps -ms > file.ps
Because it contains tabs, you'll need to redirect psql output or use
"script", rather than pasting from a terminal window, due to the tabs
which can be replaced with spaces.

now survives a database restart. Per previous discussion, this is
essential for PITR log shipping and for 2PC.
