<P>In pre-8.0 releases, indexes often can not be used unless the data
types exactly match the index's column types. This is particularly
true of int2, int8, and numeric column indexes.</P>
use of already-freed strings, other silliness. Also fix reporting of
config file syntax errors so that it actually works reasonably well
(eg, points at the correct line). Use palloc instead of malloc for
temporary storage to reduce code clutter.
not supposed to (fixes problem with postmaster aborting due to mistaken
postgresql.conf change); don't call superuser() when not inside a
transaction (fixes coredump when, eg, try to set log_statement from
PGOPTIONS); some message style guidelines enforcement.
default tablespace --- they should always go in the database's default
tablespace. Adjust heap_create() API so that it is passed the relkind
to make this easier; should simplify any further tweaking of the same
sort.
to allow DBA to choose the form in which log filenames reflect the
current time. Also allow for truncating instead of appending to
pre-existing files --- this is convenient when the log filename pattern
rewrites the same names cyclically. Per Ed L.
during replay of CREATE DATABASE as well as the first time around.
Else it's possible that the copy operation will copy obsolete blocks.
We are still a long way from guaranteeing anything about using a
recently-written database as a CREATE template, but this seems needed
to ensure the existing behavior holds up during replay.
Fix TablespaceCreateDbspace() to be able to create a dummy directory
in place of a dropped tablespace's symlink. This eliminates the open
problem of a PANIC during WAL replay when a replayed action attempts
to touch a file in a since-deleted tablespace. It also makes for a
significant improvement in the usability of PITR replay.
a more tolerable limit on the number of subtransactions or deleted files
in COMMIT and ABORT records. Buy back the extra space by eliminating the
xl_xact_prev field, which isn't being used for anything and is rather
unlikely ever to be used for anything.
This does not force initdb, but you do need to do pg_resetxlog if you
want to upgrade an existing 8.0 installation without initdb.
Win32 WaitForMultipleObjects:
ret = WaitForMultipleObjects(win32_numChildren, win32_childHNDArray,
FALSE, 0);
Problem is 'win32_numChildren' could be more then 64 ( function supports
), problem basically arise ( kills postgres ) when you create more then
64 connections and terminate some of them sill leaving more then 64.
