then we should export a reasonable set of the supporting routines too.

f1b3d5b02d Remove unused function SSL_CTX_set_tmp_dh_callback() from libpq:
In the SSL code in libpq it does some processing with DH parameters:

SSL_CTX_set_tmp_dh_callback()

This function is marked as server use only[1], the client always uses
the DH parameters in the server, so all the code in the client dealing
with the DH parameters is useless. This patch removes it.

It's not clear why the code was added in the first place, it's been
there almost since the beginning[2]. At the time there was a suggestion
of merging the front-end and backend SSL code, but looking at the
changes since, that seems unlikely.

As a further example, the s_server program allows you to specify DH
params, but s_client doesn't. In the GnuTLS documentation under
gnutls_dh_params_generate2() it says[3]:

  Also note that the DH parameters are only useful to servers. Since
  clients use the parameters sent by the server, it's of no use to call
  this in client side.

02eb8f4f5c Use schema search path to find the first matching contraint name for SET
CONSTRAINT, rather than affecting all constraints in all schemas (which
is what we used to do).  Also allow schema specifications.

944a17bf9f Delay write of pg_stats file to once every five minutes, during
shutdown, or when requested by a backend:

It changes so the file is only written once every 5 minutes (changeable
of course, I just picked something) instead of once every half second.
It's still written when the stats collector shuts down, just as before.
And it is now also written on backend request. A backend requests a
rewrite by simply sending a special stats message. It operates on the
assumption that the backends aren't actually going to read the
statistics file very often, compared to how frequent it's written today.

3/ Columns reordered more logically
4/ 'Blockid' column removed
5/ Free bytes column renamed to just 'bytes' instead of 'blockfreebytes'

486f994be7 Revise large-object access routines to avoid running with CurrentMemoryContext
set to the large object context ("fscxt"), as this is inevitably a source of
transaction-duration memory leaks.  Not sure why we'd not noticed it before;
maybe people weren't touching a whole lot of LOs in the same transaction
before the 8.1 pg_dump changes.  Per report from Wayne Conrad.

Backpatched as far as 8.1, but the problem doubtless goes all the way back.
I'm disinclined to spend the time to try to verify that the older branches
would still work if patched, seeing that this code was significantly modified
for 8.0 and again for 8.1, and that we don't have any trouble reports before
8.1.  (Maybe the leaks were smaller before?)

d2896a9ed1 Arrange to cache btree metapage data in the relcache entry for the index,
thereby saving a visit to the metapage in most index searches/updates.
This wouldn't actually save any I/O (since in the old regime the metapage
generally stayed in cache anyway), but it does provide a useful decrease
in bufmgr traffic in high-contention scenarios.  Per my recent proposal.

1e3593ce16 The 8.1 planner removes WHERE quals from the plan when the quals are
implied by the predicate of a partial index being used to scan a table.
However, this optimization is unsafe in an UPDATE, DELETE, or SELECT FOR
UPDATE query, because the quals need to be rechecked by EvalPlanQual if
there's an update conflict.  Per example from Jean-Samuel Reynaud.

c880f9aeb2 Update SQL-standard INTERVAL item:
o Support ISO INTERVAL syntax if units cannot be determined from
          the string, and are supplied after the string

          The SQL standard states that the units after the string specify
          the units of the string, e.g. INTERVAL '2' MINUTE should
          return '00:02:00'.  The current behavior has the units
          restrict the interval value to the specified unit or unit range,
          INTERVAL '70' SECOND returns '00:00:10'.

          For syntax that isn't uniquely ISO or PG syntax, like '1' or
          '1:30', treat as ISO if there is a range specification clause,
          and as PG if there no clause is present, e.g. interpret
          '1:30' MINUTE TO SECOND as '1 minute 30 seconds', and
          interpret '1:30' as '1 hour, 30 minutes'.

          This makes common cases like SELECT INTERVAL '1' MONTH
          SQL-standard results.  The SQL standard supports a limited
          number of unit combinations and doesn't support unit names
          in the string.  The PostgreSQL syntax is more flexible in
          the range of units supported, e.g. PostgreSQL supports
          '1 year 1 hour', while the SQL standard does not.
