Make pg_dump handle the new privileges. 

Don't hardcode the maximum accepted server version, use PG_VERSION instead.
Install a notice processor so notices are handled like error messages.
Word smithing.

* Modifications - 6/10/96 - dave@bensoft.com - version 1.13.dhb
*
* Applied 'insert string' patch from "Marc G. Fournier" <scrappy@ki.net>
* Added '-t table' option
* Added '-a' option
* Added '-da' option
*
* Modifications - 6/12/96 - dave@bensoft.com - version 1.13.dhb.2
*
* - Fixed dumpTable output to output lengths for char and varchar types!
* - Added single. quote to twin single quote expansion for 'insert' string
* mode.
*
* Modifications - 7/26/96 - asussman@vidya.com
*
* - Fixed ouput lengths for char and varchar type where the length is variable (-1)
*
* Modifications - 6/1/97 - igor@sba.miami.edu
* - Added functions to free allocated memory used for retrieving
* indexes,tables,inheritance,types,functions and aggregates.
* No more leaks reported by Purify.
*
*
* Modifications - 1/26/98 - pjlobo@euitt.upm.es
* - Added support for password authentication
*
* Modifications - 28-Jun-2000 - Philip Warner pjw@rhyme.com.au
* - Used custom IO routines to allow for more
* output formats and simple rearrangement of order.
* - Discouraged operations more appropriate to the 'restore'
* operation. (eg. -c "clear schema" - now always dumps
* commands, but pg_restore can be told not to output them).
* - Added RI warnings to the 'as insert strings' output mode
* - Added a small number of comments
* - Added a -Z option for compression level on compressed formats
* - Restored '-f' in usage output
*
*
* Modifications - 17-Jul-2000 - Philip Warner pjw@rhyme.com.au
* - Support for BLOB output.
* - Sort archive by OID, put some items at end (out of OID order)
*
* 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)
*
* Modifications - 14-Sep-2000 - pjw@rhyme.com.au
* Use symbols for tests on relkind (ie. use RELKIND_VIEW, not 'v')
* Support for relkind = RELKIND_VIEW.
* Fix bug in support for -b option (== --blobs).
* Dump views as views (using 'create view').
* Remove 'isViewRule' since we check the relkind when getting tables.
* Now uses temp table 'pgdump_oid' rather than 'pg_dump_oid' (errors otherwise).
*
* Modifications - 02-Oct-2000 - pjw@rhyme.com.au
*
* - Be more paranoid when getting views: call get_viewdef in separate statement
* so we can be more informative in error messages.
* - Support for 'isstrict' procedure attribute.
* - Disable --blobs and --table since (a) it's a pain to get ONLY the blobs for the
* table with the currently implementation, and (b) it's not clear how to restore
* a partial BLOB backup (given the current OID-based BLOB implementation).
*
* Modifications - 04-Jan-2001 - pjw@rhyme.com.au
*
* - Check ntuples == 1 for various SELECT statements.
* - Fix handling of --tables=* (multiple tables never worked properly, AFAICT)
*
* Modifications - 13-Feb-2001 - pjw@rhyme.com.au
*
* - Fix help output: replace 'f' with 't' and change desc.
* - Add extra arg to formatStringLiteral to specify how to handle LF & TAB.
* I opted for encoding them except in procedure bodies.
* - Dump relevant parts of sequences only when doing schemaOnly & dataOnly
* - Prevent double-dumping of sequences when dataOnly.
*
* Modifications - 19-Mar-2001 - pjw@rhyme.com.au
*
* - Remove fmtId calls for all ArchiveEntry name fields. This fixes
* quoting problems in trigger enable/disable code for mixed case
* table names, and avoids commands like 'pg_restore -t '"TblA"''
*
* Modifications - 31-Mar-2001 - pjw@rhyme.com.au
*
* - Dump dependency information in dumpType. This is necessary
* because placeholder types will have an OID less than the
* OID of the type functions, but type must be created after
* the functions.
*
* Modifications - 4-Apr-2001 - pjw@rhyme.com.au
*
* - Don't dump CHECK constraints with same source and names both
* starting with '$'.
*
* Modifications - 10-May-2001 - pjw@rhyme.com.au
*
* - Don't dump COMMENTs in data-only dumps
* - Fix view dumping SQL for V7.0
* - Fix bug when getting view oid with long view names
