generated from subquery outputs: use the type info stored in the Var
itself. To avoid making ExecEvalVar and slot_getattr more complex
and slower, I split out the whole-row case into a separate ExecEval routine.
type ID information even when it's a record type. This is needed to
handle whole-row Vars referencing subquery outputs. Per example from
Richard Huxton.
optimization for subquery and function scan nodes: we can't just do it
unconditionally, we still have to check whether there is any need for
a whole-row Var. I had been thinking that these node types couldn't
have any system columns, which is true, but that loop is also checking
for attno zero, ie, whole-row Var. Fix comment to not be so misleading.
Per test case from Richard Huxton.
fix problems with replacement-string backslashes that aren't followed by
one of the expected characters, avoid giving the impression that
replace_text_regexp() is meant to be called directly as a SQL function,
etc.
if there isn't one already open. Upon dblink_close, only commit
the open transaction if it was started by dblink_open, and only
then when all cursors opened by dblink_open are closed. The transaction
accounting is done individually for all named connections, plus
the persistent unnamed connection.
the facility has been set, the facility gets set to LOCAL0 and cannot
be changed later. This seems reasonably plausible to happen, particularly
at higher debug log levels, though I am not certain it explains Han Holl's
recent report. Easiest fix is to teach the code how to change the value
on-the-fly, which is nicer anyway. I made the settings PGC_SIGHUP to
conform with log_destination.
regression=# select '23:59:59.9'::time(0);
time
----------
24:00:00
(1 row)
This is bad because:
regression=# select '24:00:00'::time(0);
ERROR: date/time field value out of range: "24:00:00"
The last example now works.
of client_min_messages (fatal + panic) are valid and also fixes a slight
issue with how psql tried to display error messages that aren't sent to
the client.
We often tell people to ignore errors in response to requests for things
like "drop if exists", but there's no good way to completely hide this
without upping client_min_messages past ERROR. When running a file like
SET client_min_messages TO 'FATAL';
DROP TABLE doesntexist;
with "psql -f filename" you get an error prefix of
"psql:/home/username/filename:3" even though there is no error message to
prefix because it isn't sent to the client.

This makes the error messages for PREPARE TRANSACTION, COMMIT PREPARED
etc. match the docs, which talk about "transaction identifier" not
"gid" or "global transaction identifier".

WAL and the interaction of the new full_page_writes parameter with PITR.
The too-small WAL first sect1 has been merged with the one following
sect1 for clarity.
Some minor comments have been made in the WAL config section also.
Passes SGML make and proofread for typos.
