interaction between ld, readline, termcap, and psql. The symptom is psql
failing with this error on startup:

    symbol lookup error: /usr/lib64/libreadline.so.4: undefined symbol: BC

I'm still trying to find the best way to solve this, but in the mean time
I'm reverting the patch in order to unbreak FC3.

which is neither needed by nor related to that header.  Remove the bogus
inclusion and instead include the header in those C files that actually
need it.  Also fix unnecessary inclusions and bad inclusion order in
tsearch2 files.

significant regardless of the value of lanispl.

check for reserved words.

feeds properly.

associated with a hashtable is allocated in that hashtable's private
context, so that hash_destroy only has to destroy the context and not
do any retail pfree's; and tighten the inner loop of hash_seq_search.

too, but that one is in my way at the moment.)

is a way to recover from disabling connections to all databases at once.

understands arg control, so we don't need our own.  In fact, it
also uses macros that conflict with ours, so we _can't_ use
our own.

we are at it.  Add release notes.

executable against the maximal set of libraries it might need. So for
example, if one executable requires `libreadline', all executables are
linked against it.

The easiest fix is to make use of GNU ld's --as-needed flag, which
ignores linker arguments that are not actually needed by the specified
object files. The attached patch modifies configure to check for this
flag (when using GNU ld), and if ld supports it, adds the flag to
LDFLAGS (we need to do the check since only relatively recent versions
of GNU ld support this capability). Currently only GNU ld is supported;
I'm not aware of any other linkers that support this functionality.

startup to end, rather than re-opening it in each MultiExecBitmapIndexScan
call.  I had foolishly thought that opening/closing wouldn't be much
more expensive than a rescan call, but that was sheer brain fade.

This seems to fix about half of the performance lossage reported by
Sergey Koposov.  I'm still not sure where the other half went.

moment this has no particular use except to allow table rows to be
passed to record_out(), but that case seems to be useful in itself
per recent example from Elein.  Further down the road we could look
at letting PL functions be declared to accept RECORD parameters.

so that restart doesn't fail when old postmaster died unbetimes.

are creating a new MultiXactId from two regular XIDs.  The original
coding was unnecessarily complicated and didn't save any code anyway.

output area as INTERNAL not CSTRING.  This is to prevent people from
calling the functions by hand.  This is a permanent solution for the
back branches but I hope it is just a stopgap for HEAD.

that return INTERNAL without also having INTERNAL arguments.  Since the
functions in question aren't meant to be called by hand anyway, I just
redeclared them to take 'internal' instead of 'text'.  Also add code
to ProcedureCreate() to enforce the restriction, as I should have done
to start with :-(

to produce when running the executor. This is consistent with the internal
executor APIs (such as ExecutorRun), which also use a long for this purpose.
It also allows FETCH_ALL to be passed -- since FETCH_ALL is defined as
LONG_MAX, this wouldn't have worked on platforms where int and long are of
different sizes. Per report from Tzahi Fadida.

only one argument.  (Per recent discussion, the option to accept multiple
arguments is pretty useless for user-defined types, and would be a likely
source of security holes if it was used.)  Simplify call sites of
output/send functions to not bother passing more than one argument.
