a descriptor that uses the current transaction snapshot, rather than
SnapshotNow as it did before (and still does if INV_WRITE is set).
This means pg_dump will now dump a consistent snapshot of large object
contents, as it never could do before. Also, add a lo_create() function
that is similar to lo_creat() but allows the desired OID of the large
object to be specified. This will simplify pg_restore considerably
(but I'll fix that in a separate commit).

patch adds missing checks to the call sites of malloc(), strdup(),
PQmakeEmptyPGresult(), pqResultAlloc(), and pqResultStrdup(), and updates
the documentation. Per original report from Volkan Yazici about
PQmakeEmptyPGresult() not checking for malloc() failure.

These contain the SQLSTATE and error message of the current exception,
respectively. They are scope-local variables that are only defined
in exception handlers (so attempting to reference them outside an
exception handler is an error). Update the regression tests and the
documentation.
Also, do some minor related cleanup: export an unpack_sql_state()
function from the backend and use it to unpack a SQLSTATE into a
string, and add a free_var() function to pl_exec.c
Original patch from Pavel Stehule, review by Neil Conway.

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

pg_restore. It restores the given schemaname only. It can be used in
conjunction with the -t and other switches to make the selection very
fine grained.

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.

as well as the existing pg_catalog entries for prefix and postfix %.
These have never been documented, though they did appear in one old
regression test. This avoids surprising behavior in cases like
"SELECT -25 % -10". Per recent discussion.
Note: although there is a catalog change here, I did not force initdb
since there's no harm in leaving the inaccessible entries in one's
copy of pg_operator.

transaction IDs, rather than like subtrans; in particular, the information
now survives a database restart. Per previous discussion, this is
essential for PITR log shipping and for 2PC.

This allows the result of executing a SELECT to be assigned to a row
variable, record variable, or list of scalars. Docs and regression tests
updated. Per Pavel Stehule, improvements and cleanup by Neil Conway.

a new PlannerInfo struct, which is passed around instead of the bare
Query in all the planning code. This commit is essentially just a
code-beautification exercise, but it does open the door to making
larger changes to the planner data structures without having to muck
with the widely-known Query struct.

1. Rename spi_return_next to return_next.
2. Add a new test for return_next.
3. Update the expected output.
4. Update the documentation.

postgresql.conf.
---------------------------------------------------------------------------
Here's an updated version of the patch, with the following changes:
1) No longer uses "service name" as "application version". It's instead
hardcoded as "postgres". It could be argued that this part should be
backpatched to 8.0, but it doesn't make a big difference until you can
start changing it with GUC / connection parameters. This change only
affects kerberos 5, not 4.
2) Now downcases kerberos usernames when the client is running on win32.
3) Adds guc option for "krb_caseins_users" to make the server ignore
case mismatch which is required by some KDCs such as Active Directory.
Off by default, per discussion with Tom. This change only affects
kerberos 5, not 4.
4) Updated so it doesn't conflict with the rendevouz/bonjour patch
already in ;-)
