only one way of planning inheritance, expand inheritance sets during the

concept, use the data structure to plan joins against inheritance sets more

Per a bug report from Theo Schlossnagle, plperl_return_next() leaks
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.

Tweak initdb to reduce verbosity of progress messages, by printing just
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.

Snowball multibyte. It's a pity, but snowball sources is very diferent for multibyte and

Fix display of whole-row Var appearing at the top level of a SELECT list.
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.

Clean up the INET-vs-CIDR situation. Get rid of the internal is_cidr flag
and rely exclusively on the SQL type system to tell the difference between
the types. Prevent creation of invalid CIDR values via casting from INET
or set_masklen() --- both of these operations now silently zero any bits
to the right of the netmask. Remove duplicate CIDR comparison operators,
letting the type rely on the INET operators instead.

Remove the no-longer-useful BTItem/BTItemData level of structure, and

they have been for a very long time. This is mostly just an exercise
in removing extraneous notation, but it does save a palloc/pfree cycle

Remove unnecessary PQconsumeInput call from PQputCopyData; it's redundant

Avoiding a kernel call per PQputCopyData call helps COPY speed materially.

Instead of using a numberOfRequiredKeys count to distinguish required
and non-required keys in a btree index scan, mark the required scankeys
with private flag bits SK_BT_REQFWD and/or SK_BT_REQBKWD. This seems
at least marginally clearer to me, and it eliminates a wired-into-the-
data-structure assumption that required keys are consecutive. Even though
that assumption will remain true for the foreseeable future, having it
in there makes the code seem more complex than necessary.
