as it appears in the schema dump, and index tags.

Reused the Expr node to hold DISTINCT which strongly resembles
 the existing OP info. Define DISTINCT_EXPR which strongly resembles
 the existing OPER_EXPR opType, but with handling for NULLs required
 by SQL99.
We have explicit support for single-element DISTINCT comparisons
 all the way through to the executor. But, multi-element DISTINCTs
 are handled by expanding into a comparison tree in gram.y as is done for
 other row comparisons. Per discussions, it might be desirable to move
 this into one or more purpose-built nodes to be handled in the backend.
Define the optional ROW keyword and token per SQL99.
 This allows single-element row constructs, which were formerly disallowed
 due to shift/reduce conflicts with parenthesized a_expr clauses.
Define the SQL99 TREAT() function. Currently, use as a synonym for CAST().

Fix pg_dump to not quote the function name in the storage tag.
Fix pg_dump so GRANT/REVOKE(ACL) tag entries are not quoted, for
	consistency.
Fix pg_restore to properly handle quotes and some spaces in -P.

wasn't really right for case where :var is at the end of the line,
was definitely not right if var expanded to empty in that case,
and failed to recalculate thislen before jumping back to rescan.

will make fixing things easier.

Thanks for the clarification.  Here is the patch.  Not much gain, but at
least it saves the next junior hacker from scratching his head ...

all places, where pd_linp is accessed.  Also introduce new macros
SizeOfPageHeaderData and BTMaxItemSize. This is just source code
cosmetic, no behaviour changed.

lines of code into internal routines (drop_relfilenode_buffers,
release_buffer) and by hiding unused routines (PrintBufferDescs,
PrintPinnedBufs) behind #ifdef NOT_USED. Remove AbortBufferIO()
declaration from bufmgr.c (already declared in bufmgr.h)

patch from 2002-06-10, is supposed to reduce the heap tuple header size
by four bytes on most architectures.  Of course it changes the on-disk
tuple format and therefore requires initdb.

This overlays cmin/cmax/xmax fields into only two fields.

files.  Was causing CVS problems.

RESTRICT/CASCADE syntax to the DROP commands that need it, and propagates
the behavioral option through the parser to the routines that execute
drops.  Doesn't do anything useful yet, but I figured I'd commit these
changes so I could get out of the parser area while working on the rest.

Committing parser changes. Note, however, that the development bison seems ot have a problem on my home machine. So these go in untested for the time being. But at least I have them in the archive.
