Add new constraint types PRIMARY, UNIQUE.

Remove TimeRange node type tag (everything else already gone).

 Probably have it wrong (dd.mm/yyyy) but can change it when we know.
 Input routines always handled it.

 Most processors should optimize this a bit better wrt cache prefetch.

 IndexStmt, IndexElem, ColumnDef).

Change reference to field inside to be compatible with new definition
 as a "node" structure rather than a specialty structure.

Implement PRIMARY KEY and UNIQUE clauses using indices.

 of integer Unix system times.

Clean up formatting of code

Integrate new functions into dumpTable


This is not tested yet...have to recompile server due to patches from
Todd...but this compiles cleanly as it stands now

An extension to the code to allow for a pg_password authentication database
that is *seperate* from the system password file

does

pg_version...

Change elog WARN to NOTICE for unimplemented constraints.

From: Herb Richter <hgr@buynet.com>

Document pg_dump -z, clean up option list.  Fix problem with libpq handling of field names uppercase code.

Add tests for strings and varchar.

 to NOTICE messages so that execution proceeds rather than halting.
 These clauses are ignored as stated in the messages.
Allow NOT NULL UNIQUE syntax (both were allowed individually before).
Allow Postgres-style casting ("::") of non-constants.

 No functional changes this time!

 btree support functions. Don't know why this was that way, but would
 assume that these should be consistant with all other types with
 hash support. Regression tests OK.
Change a few comments and field alignment to make things more readable.

 certainly OK for datetime since it is a float8 and should be OK for
 timespan since the first field within timespan is a float8.
Use float8 hash function for time type (rather than char8).

 since I've run ./duplicate_oids (and found no problems) in the last
 couple of months.
Add and modify some DESCR() entries to describe functions.

 Don't know why these few were not already this way, and don't know if
  there is some hidden problem with this, but assume it was done
  accidentally as entries were copied from other operators.
 Regression tests are OK, but...
Move one block of declaration source to keep OIDs in increasing order.
 Did not change OID values, just moved source code.

 Lost these when some include files were reorganized.
 Regression test could not compile.
