52667d56a3 Rethink the locking mechanisms used for CREATE/DROP/RENAME DATABASE.
The former approach used ExclusiveLock on pg_database, which being a
cluster-wide lock meant only one of these operations could proceed at
a time; worse, it also blocked all incoming connections in ReverifyMyDatabase.
Now that we have LockSharedObject(), we can use locks of different types
applied to databases considered as objects.  This allows much more
flexible management of the interlocking: two CREATE DATABASEs need not
block each other, and need not block connections except to the template
database being used.  Similarly DROP DATABASE doesn't block unrelated
operations.  The locking used in flatfiles.c is also much narrower in
scope than before.  Per recent proposal.

e57345975c Clean up API for ambulkdelete/amvacuumcleanup as per today's discussion.
This formulation requires every AM to provide amvacuumcleanup, unlike before,
but it's surely a whole lot cleaner.  Also, add an 'amstorage' column to
pg_am so that we can get rid of hardwired knowledge in DefineOpClass().

82a2881c5b Code review for GRANT CONNECT patch. Spell the privilege as CONNECT not
CONNECTION, fix a number of places that were missed (eg pg_dump support),
avoid executing an extra search of pg_database during startup.

986085a7f0 Improve the representation of FOR UPDATE/FOR SHARE so that we can
support both FOR UPDATE and FOR SHARE in one command, as well as both
NOWAIT and normal WAIT behavior.  The more general code is actually
simpler and cleaner.

is what we used to do).  Also allow schema specifications.

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.

efe3de07e9 Removes or minimizes some documentation mentions of backward
compatibility for release 7.2 and earlier.  I have not altered any
mentions of release 7.3 or later.  The release notes were not modified,
so the changes are still documented, just not in the main docs.

1b4504ced2 Remove from TODO ability to edit pg_hba.conf, but add GRANT connection
permission item:

< 	o %Allow pg_hba.conf settings to be controlled via SQL
> 	o %Allow per-database permissions to be set via GRANT
< 	  This would add a function to load the SQL table from
<           pg_hba.conf, and one to writes its contents to the flat file.
< 	  The table should have a line number that is a float so rows
< 	  can be inserted between existing rows, e.g. row 2.5 goes
< 	  between row 2 and row 3.
> 	  Allow database connection checks based on GRANT rules in
> 	  addition to the existing access checks in pg_hba.conf.

5bd59b9c0a Document that errors are not output by log_statement (was they were in
8.0), and add as suggestion to use log_min_error_statement for this
purpose.  I also fixed the code so the first EXECUTE has it's prepare,
rather than the last which is what was in the current code.  Also remove
"protocol" prefix for SQL EXECUTE output because it is not accurate.
