to the left of the actual bool value.  While in most cases there won't be
any, our support for old-style user-defined functions violates the C spec
to the extent of calling functions that might return char or short through
a function pointer declared to return "char *", which we then coerce to
Datum.  It is not surprising that the result might contain garbage
high-order bits ... what is surprising is that we didn't see such cases
long ago.  Per report from Magnus.

search_path that was active when the plan was first made.  To do this,
improve namespace.c to support a stack of "override" search path settings
(we must have a stack since nested replan events are entirely possible).
This facility replaces the "special namespace" hack formerly used by
CREATE SCHEMA, and should be able to support per-function search path
settings as well.

This is necessary to support JIS X 0213 <--> UTF-8 conversion.

Also remove headers for old sysv semaphore emulation that were forgotten
when that was changed about a year ago.

of a multi-statement simple-Query message.  This bug goes all the way
back, but unfortunately is not nearly so easy to fix in existing releases;
it is only the recent ProcessUtility API change that makes it fixable in
HEAD.  Per report from William Garrison.

doesn't exist.  This allows DROP to be used to clean out the pg_tablespace
catalog entry in a situation where a previous DROP attempt failed before
committing but after having removed the directories and symlink.

Per report from William Garrison.  Even though his test case depends on an
unrelated bug in PreventTransactionChain, it's certainly possible for this
situation to arise due to other problems, eg a system crash at just the
right time.

full words support, per report from Mark Stosberg.

of palloc instead of malloc, which means a list can be freed simply by deleting
the memory context that contains it.

sizeof(wchar_t) = 2 instead of 4.

First, genericcostestimate() was being way too liberal about including
partial-index conditions in its selectivity estimate, resulting in
substantial underestimates for situations such as an indexqual "x = 42"
used with an index on x "WHERE x >= 40 AND x < 50".  While the code is
intentionally set up to favor selecting partial indexes when available,
this was too much...

Second, choose_bitmap_and() was likewise easily fooled by cases of this
type, since it would similarly think that the partial index had selectivity
independent of the indexqual.

Fixed by using predicate_implied_by() rather than simple equality checks
to determine redundancy.  This is a good deal more expensive but I don't
see much alternative.  At least the extra cost is only paid when there's
actually a partial index under consideration.

Per report from Jeff Davis.  I'm not going to risk back-patching this,
though.

< * Add NUMERIC division operator that doesn't round?

<   Currently NUMERIC _rounds_ the result to the specified precision.
<   This means division can return a result that multiplied by the

<     SELECT (10::numeric(2,0) / 6::numeric(2,0))::numeric(2,0) * 6;

  one column or expression indexes, perhaps using per-index statistics
