(respectively) to rename yylex and related symbols.  Some were doing
it this way already, while others used not-too-reliable sed hacks in
the Makefiles.  It's all nice and consistent now.

not likely ever to be implemented seeing it's been removed from SQL2003.
This allows getting rid of the 'filter' version of yylex() that we had in
parser.c, which should save at least a few microseconds in parsing.

   - new function justify_interval(interval)
   - modified function justify_hours(interval)
   - modified function justify_days(interval)

These functions are defined to meet the requirements as discussed in
this thread.  Specifically:

   - justify_hours makes certain the sign bit on the hours
     matches the sign bit on the days.  It only checks the
     sign bit on the days, and not the months, when
     determining if the hours should be positive or negative.
     After the call, -24 < hours < 24.

   - justify_days makes certain the sign bit on the days
     matches the sign bit on the months.  It's behavior does
     not depend on the hours, nor does it modify the hours.
     After the call, -30 < days < 30.

   - justify_interval makes sure the sign bits on all three
     fields months, days, and hours are all the same.  After
     the call, -24 < hours < 24 AND -30 < days < 30.

  While playing with this patch under 8.1.2 at home I discovered a
  mistake in how I manually applied one of the hunks to fe-auth.c.
  Basically, the base code had changed and so the patch needed to be
  modified slightly.  This is because the code no longer either has a
  freeable pointer under 'name' or has 'name' as NULL.

  The attached patch correctly frees the string from pg_krb5_authname
  (where it had been strdup'd) if and only if pg_krb5_authname returned
  a string (as opposed to falling through and having name be set using
  name = pw->name;).  Also added a comment to this effect.

Backpatch to 8.1.X.

returning "ASCII code of the first character of the argument"

(see
http://www.postgresql.org/docs/8.1/interactive/functions-string.html,
Table  9-6. "Other String Functions").

Presumably this should read "ASCII code of the first byte of the
argument",
which is what is returned when the argument is a multi-byte character
(although then with UTF-8 at least that might not necessarily be an
ASCII
code).

statements before the multi-line statement, rather than inside the
multi-line statement.

columns of the grouping clause to avoid redundant sorts. The optimizer
is not currently capable of doing this, so this patch implements a
simple hack in the analysis phase (transformGroupClause): if any
subset of the GROUP BY clause matches a prefix of the ORDER BY list,
that prefix is moved to the front of the GROUP BY clause. This
shouldn't change the semantics of the query, and allows a redundant
sort to be avoided for queries like "GROUP BY a, b ORDER BY b".

Patch by Joachim Wieland, somewhat reworked for clarity and portability.

This is consistent with the standard definition of fopen().

In particular, ensure that enlargement of the memtuples[] array doesn't
fall foul of MaxAllocSize when work_mem is very large, and don't bother
enlarging it if that would force an immediate switch into 'tape' mode anyway.

we'll go over to disk-based sort if we reach that limit.
This fixes Stefan Kaltenbrunner's observation that sorting can suffer an
'invalid memory alloc request size' failure when sort_mem is set large
enough.  It's unfortunately not so easy to fix in 8.1 ...
