internally $$ strings are converted to single-quote strings.

In ecpg, output newlines in commands using standard C escapes, rather
than using literal newlines, which is not portable.

have the directory for the configure test.

thereby sharing code with the inheritance case.  This puts the UNION-ALL-view
approach to partitioned tables on par with inheritance, so far as constraint
exclusion is concerned: it works either way.  (Still need to update the docs
to say so.)  The definition of "simple UNION ALL" is a little simpler than
I would like --- basically the union arms can only be SELECT * FROM foo
--- but it's good enough for partitioned-table cases.

MemSet on AIX by setting MEMSET_LOOP_LIMIT to zero.

Add optimization to skip MemSet tests in MEMSET_LOOP_LIMIT == 0 case and
just call memset() directly.

Disallow backslash as the delimiter in non-CVS mode.

Backpatch.

set, causing a segfault if log_min_messages was set below debug2 and our
own snprintf.c was being used.

Also alway strdup() progname.

Backpatch to 8.1.X and 8.0.X.

inheritance trees on-the-fly, which pretty well constrained us to considering
only one way of planning inheritance, expand inheritance sets during the
planner prep phase, and build a side data structure that can be consulted
later to find which RTEs are members of which inheritance sets.  As proof of
concept, use the data structure to plan joins against inheritance sets more
efficiently: we can now use indexes on the set members in inner-indexscan
joins.  (The generated plans could be improved further, but it'll take some
executor changes.)  This data structure will also support handling UNION ALL
subqueries in the same way as inheritance sets, but that aspect of it isn't
finished yet.

constraints before FOREIGN KEY constraints that depended on them.  Originally

to avoid sharing substructure with the lower-level indexquals.  This is
currently only an issue if there are SubPlans in the indexquals, which is
uncommon but not impossible --- see bug #2218 reported by Nicholas Vinen.
We use the same kluge for indexqual vs indexqualorig in the index scans
themselves ... would be nice to clean this up someday.

requested sort order.  It was assuming that build_index_pathkeys always
generates a pathkey per index column, which was not true if implied equality
deduction had determined that two index columns were effectively equated to
each other.  Simplest fix seems to be to install an option that causes
build_index_pathkeys to support this behavior as well as the original one.
Per report from Brian Hirt.

Undo perl's nasty locale setting on Windows. Since we can't do that as
elsewhere by setting the environment appropriately, we make perl do it
right after interpreter startup by calling its POSIX::setlocale().

memory in the executor's per-query memory context. It also inefficient:
it invokes get_call_result_type() and TupleDescGetAttInMetadata() for
every call to return_next, rather than invoking them once (per PL/Perl
function call) and memoizing the result.

This patch makes the following changes:

- refactor the code to include all the "per PL/Perl function call" data
inside a single struct, "current_call_data". This means we don't need to
save and restore N pointers for every recursive call into PL/Perl, we
can just save and restore one.

- lookup the return type metadata needed by plperl_return_next() once,
and then stash it in "current_call_data", so as to avoid doing the
lookup for every call to return_next.

- create a temporary memory context in which to evaluate the return
type's input functions. This memory context is reset for each call to
return_next.

The patch appears to fix the memory leak, and substantially reduces
the overhead imposed by return_next.

one 'creating subdirectories' message instead of one per subdirectory.
The original decision to print something for each subdirectory was made
when there were only one or two of 'em; we have way too many now.
Per discussion.

singlebyte encodings, so we should have snowball for every encodings.

I hope that finalize multibyte support work in tsearch2, but testing is needed...

While we normally prefer the notation "foo.*" for a whole-row Var, that does
not work at SELECT top level, because in that context the parser will assume
that what is wanted is to expand the "*" into a list of separate target
columns, yielding behavior different from a whole-row Var.  We have to emit
just "foo" instead in that context.  Per report from Sokolov Yura.
