Log Message:
Update postgresql and related packages to 7.2.  Pkgsrc changes from the
previous version include removing Makefile.ssl and some patches that have
been integrated into this release of PostgreSQL.  We leave open the question
of when to byte-compile the Python modules for the PyGreSQL interface and
just do it as before, although we should consider doing the compilation as a
post-install step to ensure that the timestamps are correct.  We also
reorder some lines in the Makefile to include Makefile.common below certain
definitions (GNU_CONFIGURE, USE_BUILDLINK_ONLY) as they may possibly trigger
different portions of Makefile.common.

*** Please note that a dump/restore is required to migrate an existing ***
*** PostgreSQL installation to 7.2.                                    ***

Major changes from version 7.1.3 are geared toward improving use in
high-volume applications and include:

   VACUUM
	   Vacuuming no longer locks tables, thus allowing normal user access
           during the vacuum. A new "VACUUM FULL" command does old-style
           vacuum by locking the table and shrinking the on-disk copy of the
           table.

   Transactions
           There is no longer a problem with installations that exceed four
           billion transactions.

   OID's
           OID's are now optional. Users can now create tables without OID's
           for cases where OID usage is excessive.

   Optimizer
           The system now computes histogram column statistics during
           "ANALYZE", allowing much better optimizer choices.

   Security
           A new MD5 encryption option allows more secure storage and
           transfer of passwords. A new Unix-domain socket authentication
           option is available on Linux and BSD systems. PAM authentication
           is also available.

   Statistics
           Administrators can use the new table access statistics module to
           get fine-grained information about table and index usage.
