Fix an error in make_outerjoininfo introduced by my patch of 30-Aug: the code
neglected to test whether an outer join's join-condition actually refers to
the lower outer join it is looking at.  (The comment correctly described what
was supposed to happen, but the code didn't do it...)  This often resulted in
adding an unnecessary constraint on the join order of the two outer joins,
which was bad enough.  However, it also seems to expose a performance
problem in an older patch (from 15-Feb): once we've decided that there is a
join ordering constraint, we will start trying clauseless joins between every
combination of rels within the constraint, which pointlessly eats up lots of

Tom Lane [Wed, 24 Oct 2007 18:37:09 +0000 (18:37 +0000)]
Fix UPDATE/DELETE WHERE CURRENT OF to support repeated update and update-
then-delete on the current cursor row.  The basic fix is that nodeTidscan.c
has to apply heap_get_latest_tid() to the current-scan-TID obtained from the
cursor query; this ensures we get the latest row version to work with.
However, since that only works if the query plan is a TID scan, we also have
to hack the planner to make sure only that type of plan will be selected.
(Formerly, the planner might decide to apply a seqscan if the table is very
small.  This change is probably a Good Thing anyway, since it's hard to see
how a seqscan could really win.)  That means the execQual.c code to support
CurrentOfExpr as a regular expression type is dead code, so replace it with
just an elog().  Also, add regression tests covering these cases.  Note

17 years agoFix the inadvertent libpq ABI breakage discovered by Martin Pitt: the
Tom Lane [Sat, 13 Oct 2007 20:18:42 +0000 (20:18 +0000)]
Fix the inadvertent libpq ABI breakage discovered by Martin Pitt: the
renumbering of encoding IDs done between 8.2 and 8.3 turns out to break 8.2
initdb and psql if they are run with an 8.3beta1 libpq.so.  For the moment
we can rearrange the order of enum pg_enc to keep the same number for
everything except PG_JOHAB, which isn't a problem since there are no direct
references to it in the 8.2 programs anyway.  (This does force initdb
unfortunately.)

Going forward, we want to fix things so that encoding IDs can be changed
without an ABI break, and this commit includes the changes needed to allow
libpq's encoding IDs to be treated as fully independent of the backend's.
The main issue is that libpq clients should not include pg_wchar.h or
otherwise assume they know the specific values of libpq's encoding IDs,
since they might encounter version skew between pg_wchar.h and the libpq.so
they are using.  To fix, have libpq officially export functions needed for
encoding name<=>ID conversion and validity checking; it was doing this
anyway unofficially.

It's still the case that we can't renumber backend encoding IDs until the
next bump in libpq's major version number, since doing so will break the
8.2-era client programs.  However the code is now prepared to avoid this
type of problem in future.

Note that initdb is no longer a libpq client: we just pull in the two
source files we need directly.  The patch also fixes a few places that
were being sloppy about checking for an unrecognized encoding name.
