First pass at schema-fying pg_dump/pg_restore. Much to do still, 

but the basic capability seems to work.

* Modifications 14-Sep-2000 - pjw@rhyme.com.au

* is returned then fmtId is called on the string.

* Modifications 4-Apr-2001 - pjw@rhyme.com.au

* BEWARE: Since fmtId uses a static buffer, using 'useBaseTypeName' on more

*
* Modifications - 28-Jun-2000 - pjw@rhyme.com.au
*
* Initial version.
*
*
* Modifications - 28-Jul-2000 - pjw@rhyme.com.au (1.45)
*
* Added --create, --no-owner, --superuser, --no-reconnect (pg_dump & pg_restore)
* Added code to dump 'Create Schema' statement (pg_dump)
* Don't bother to disable/enable triggers if we don't have a superuser (pg_restore)
* Cleaned up code for reconnecting to database.
* Force a reconnect as superuser before enabling/disabling triggers.
*
* Modifications - 31-Jul-2000 - pjw@rhyme.com.au (1.46, 1.47)
* Added & Removed --throttle (pg_dump)
* Fixed minor bug in language dumping code: expbuffres were not being reset.
* Fixed version number initialization in _allocAH (pg_backup_archiver.c)
* Added second connection when restoring BLOBs to allow temp. table to survive
* (db reconnection causes temp tables to be lost).

* NOTES
*
* Modifications - 04-Jan-2001 - pjw@rhyme.com.au
*
* - Check results of PQ routines more carefully.
*
* Modifications - 19-Mar-2001 - pjw@rhyme.com.au
*
* - Avoid forcing table name to lower case in FixupBlobXrefs!
*
*
* Modifications - 18-Jan-2002 - pjw@rhyme.com.au
*
* - Split ExecuteSqlCommandBuf into 3 routines for (slightly) improved
* clarity. Modify loop to cater for COPY commands buried in the SQL
* command buffer (prev version assumed COPY command was executed
* in prior call). This was to fix the buf in the 'set max oid' code.
