being ratified as yet. This is certainly no longer true, it wasn't
even true in Q2/1998 when I did a little research for Date's book.
SQL/PSM had been published on 1996-12-15 as ISO/IEC 9075:4. So you
might want to update that section.

adjustments. Note that many tables are being abused with *really* long
description columns. Should probably shrink those columns to be more
concise, and move some of the info to follow-on reference notes.
\keep (keep current paragraph together). This fixes most troubles with
reference pages marked up with <refentry> tags.
Use on reference.rtf, generated by "make reference.rtf".
function arguments in join queries: copy the tuples into
TransactionCommandContext so they don't get recycled too soon. This is
horrid, but not any worse than 7.0 or before, which also leaked such
tuples until end of query. A proper fix will require allowing tuple
datums to be physically stored inside larger tuple datums, which opens
up a bunch of issues that can't realistically be solved for 7.1.1.
functions of join or subselect aliases. It'd be awfully nice if this
code knew for sure whether it was dealing with 'x.f' or 'f(x)' syntax;
maybe we can fix that in a future cycle.
or view that's been dropped and then recreated with the same name (but,
perhaps, different columns). Eventually we'd like to support this but
for now all we can do is fail cleanly, rather than possibly coredumping
if we proceed using the obsolete rule.
to specific base or join RelOptInfo nodes during planning. This preserves
the more-intuitive behavior of 7.0.* --- if you write an expensive clause
(such as a sub-select) last, it should get evaluated last. Someday we
ought to try to have some intelligence about the order of evaluation of
WHERE clauses, but for now we should not override what the user wrote.
only possible failure is in pq_flush, which will log a (better!) report
anyway --- so pq_endmessage is just cluttering the log with a redundant
entry. This matters when a client crashes partway through a large query,
since we will emit many broken-pipe reports before finishing the query
and exiting.
lists should be reverse-compiled into targetlist index numbers, because
that's the only interpretation the parser allows for a constant in these
clauses. (Ergo, the only way they could have gotten into the list in
the first place is to have come from the targetlist; so this should always
work.) Per problem report from Peter E.
join clauses. The mergejoin executor wants all the join clauses to appear
as merge quals, not as extra joinquals, for these kinds of joins. But the
planner would consider plans in which partially-sorted input paths were
used, leading to only some of the join clauses becoming merge quals.
This is fine for inner/left joins, not fine for right/full joins.
