917bbebf7f Apply a simple solution to the problem of making INSERT/UPDATE/DELETE
RETURNING play nice with views/rules.  To wit, have the rule rewriter
rewrite any RETURNING clause found in a rule to produce what the rule's
triggering query asked for in its RETURNING clause, in particular drop
the RETURNING clause if no RETURNING in the triggering query.  This
leaves the responsibility for knowing how to produce the view's output
columns on the rule author, without requiring any fundamental changes
in rule semantics such as adding new rule event types would do.  The
initial implementation constrains things to ensure that there is
exactly one, unconditionally invoked RETURNING clause among the rules
for an event --- later we might be able to relax that, but for a post
feature freeze fix it seems better to minimize how much invention we do.
Per gripe from Jaime Casanova.

04912899e7 Add new variable "server_version_num", which is almost the same as
"server_version" but uses the handy PG_VERSION_NUM which allows apps to
do things like if ($version >= 80200) without having to parse apart the
value of server_version themselves.

c2f60711d2 Create a FETCH_COUNT parameter that causes psql to execute SELECT-like
queries via a cursor, fetching a limited number of rows at a time and
therefore not risking exhausting memory.  A disadvantage of the scheme
is that 'aligned' output mode will align each group of rows independently
leading to odd-looking output, but all the other output formats work
reasonably well.  Chris Mair, with some additional hacking by moi.

0434c46db0 Invent an assign-hook mechanism for psql variables similar to the one
existing for backend GUC variables, and use this to eliminate repeated
fetching/parsing of psql variables in psql's inner loops.  In a trivial
test with lots of 'select 1;' commands, psql's CPU time went down almost
10%, although of course the effect on total elapsed time was much less.
Per discussion about how to ensure the upcoming FETCH_COUNT patch doesn't
cost any performance when not being used.

bc24d5b976 Now bind displays prepare as detail, and execute displays prepare and
optionally bind.  I re-added the "statement:" label so people will
understand why the line is being printed (it is log_*statement
behavior).

Use single quotes for bind values, instead of double quotes, and double
literal single quotes in bind values (and document that).  I also made
use of the DETAIL line to have much cleaner output.

1832cefda1 Fix pgstat_report_waiting() to not dump core if called before
pgstat_bestart() has been called; else any lock-block occurring
during InitPostgres() is disastrous.  I believe this explains
recent wasp regression failure; at least it explains the crash I
got while trying to duplicate the problem.  I also made
pgstat_report_activity() safe against the same scenario, just
in case.  The report_waiting hazard was created by my patch of
19-Aug to include waiting status in pg_stat_activity.

ae28cfe673 Partial fix for ecpg's VPATH problems. It compiles and successfully
builds all the files needed for its regression tests, but the tests
themselves fail because of diffs in the #line directives output by
ecpg itself.  Not sure what to do about that.

fcba3b82e2 Tweak trivial_subqueryscan() to consider a SubqueryScan's targetlist
trivial if it contains either Vars referencing the corresponding subplan
columns, or Consts equaling the corresponding subplan columns.  This
lets the planner eliminate the SubqueryScan in some cases generated by
generate_setop_tlist().

ea2e263539 Add new return codes SPI_OK_INSERT_RETURNING etc to the SPI API.
Fix all the standard PLs to be able to return tuples from FOO_RETURNING
statements as well as utility statements that return tuples.  Also,
fix oversight that SPI_processed wasn't set for a utility statement
returning tuples.  Per recent discussion.
