take 'em out of pg_operator.  Also remove from scan.l's set of legal
operator characters.  Update documentation.

including utility statements.  Still can't copy or compare executor
state, but at present that doesn't seem to be necessary.  This makes
it possible to execute most (all?) utility statements in plpgsql.
Had to change parsetree representation of CreateTrigStmt so that it

are running.

from Param nodes, per discussion a few days ago on pghackers.  Add new
expression node type FieldSelect that implements the functionality where
it's actually needed.  Clean up some other unused fields in Func nodes
as well.
NOTE: initdb forced due to change in stored expression trees for rules.

as MaxHeapAttributeNumber.  Increase MaxAttrSize to something more
reasonable (given what it's used for, namely checking char(n) declarations,
I didn't make it the full 1G that it could theoretically be --- 10Mb
seemed a more reasonable number).  Improve calculation of MaxTupleSize.

 are allowed in the func_name production. Otherwise, we can't define
 more like() and ilike() functions for new data types.

If the backslash default is still wanted, just pass a backslash
 to MatchText() for the two-parameter callable routines.

that RAND_MAX applies to them, since it doesn't.  Instead add a
config.h parameter MAX_RANDOM_VALUE.  This is currently set at 2^31-1
but could be auto-configured if that ever proves necessary.  Also fix
some outright bugs like calling srand() where srandom() is appropriate.

 rather than the "~~" operator; this made it easy to add ESCAPE features.
Implement ILIKE, NOT ILIKE, and the ESCAPE clause for them.
 afaict this is not MultiByte clean, but lots of other stuff isn't either.
Fix up underlying support code for LIKE/NOT LIKE.
 Things should be faster and does not require internal string copying.
Update regression test to add explicit checks for
 LIKE/NOT LIKE/ILIKE/NOT ILIKE.
Remove colon and semi-colon operators as threatened in 7.0.
Implement SQL99 COMMIT/AND NO CHAIN.
 Throw elog(ERROR) on COMMIT/AND CHAIN per spec
 since we don't yet support it.
Implement SQL99 CREATE/DROP SCHEMA as equivalent to CREATE DATABASE.
 This is only a stopgap or demo since schemas will have another
 implementation soon.
Remove a few unused production rules to get rid of warnings
 which crept in on the last commit.
Fix up tabbing in some places by removing embedded spaces.

Allow this in the parser and in pg_dump, but it is probably not enough
 for a complete solution.
Better to have the feature started then never here.

that giving pg_proc a toast table required solving the same problems
we'd have to solve for pg_class --- pg_proc is one of the relations
that gets bootstrapped in relcache.c.  Solution is to go back at the
end of initialization and read in the *real* pg_class row to replace
the phony entry created by formrdesc().  This should work as long as
there's no need to touch any toasted values during initialization,
which seems a reasonable assumption.
Although I did not add a toast-table for every single system table
with a varlena attribute, I believe that it would work to just do
ALTER TABLE pg_class CREATE TOAST TABLE.  So anyone who's really
intent on having several thousand ACL entries for a rel could do it.
NOTE: I didn't force initdb, but you must do one to see the effects
of this patch.

thing when there are multiple result relations.  Formerly, during
something like 'UPDATE foo*', foo's constraints and *only* foo's
constraints would be applied to all foo's children.  Wrong-o ...

Without this, an elog during cache-entry load leaves that catcache
unusable.  elog in that segment of code is pretty unusual but it can
happen.

multiple times in the parsetree (can happen in COALESCE or BETWEEN
contexts, for example).  This is a pretty grotty solution --- it will
do for now, but perhaps we can do better when we redesign querytrees.
What we need is a consistent policy about whether querytrees should be
considered read-only structures or not ...

 Ooops, I forget... here it is again.

- disable triggers prior to BLOB load
- better query for loading blob xrefs
- Fixes to error handling code

        - encode 'text' from database encoding to ASCII

        to_ascii('\256\341k')


 to_ascii( text, int4 )

        - encode 'text' from 'int4' encoding to ASCII

          to_ascii('\256\341k', 8)


 to_ascii( text, name )

        - encode 'text' from 'name' encoding to ASCII

          to_ascii('\256\341k', 'LATIN2')


  Now is supported LATIN1, LATIN2, WIN1250. For other character sets I
haven't good resources. Add new encoding is easy...

 If encoding is not supported returns ERROR.

 Note --- not exists total corect conversion to ASCII, this function try
        convert chars those is _probably_ interpret-able in ASCII for
        others use ' '. But for example for all Czech characters it is
        sufficient ... hmm Chinese / JAP and other complicated langs
have
        bad luck here :-(

trying to toast tuples inserted into toast tables!  Fix is two-pronged:
first, ensure all columns of a toast table are marked attstorage='p',
and second, alter the target chunk size so that it's less than the
threshold for trying to toast a tuple.  (Code tried to do that but the
expression was wrong.)  A few cosmetic cleanups in tuptoaster too.
NOTE: initdb forced due to change in toaster chunk-size.

on myself to do something about the non-self-consistency of the inet
comparison functions.  The results are probably still semantically wrong
(inet and cidr should have different comparison semantics, I think)
but at least the boolean operators now agree with each other and with
the sort order of indexes on inet/cidr.

These two routines will now ALWAYS elog() on failure, whether you ask for
a lock or not.  If you really want to get a NULL return on failure, call
the new routines heap_open_nofail()/heap_openr_nofail().  By my count there
are only about three places that actually want that behavior.  There were
rather more than three places that were missing the check they needed to
make under the old convention :-(.

We're reaching the mopup stage here (good thing too, this is getting
tedious).

result, in fact nearly the opposite of what it should, because it
was passing the not-equal operator to eqsel() which would use it to
compare the value against the most common value in the column, and
of course obtain the wrong result therefrom.  Must pass the equality
operator to eqsel() instead.  Fortunately that's easy to get from
the oprnegate link.

At this point I think it'd be possible to make float4 be pass-by-value
without too much work --- and float8 too on machines where Datum is
8 bytes.  Something to try when the mood strikes, anyway.

- 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.
- 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).
