Neil Conway 665d3736fb Clarify TODO item: we ought to implement updatable views per SQL99, not 
SQL92 (the former defines a much more ambitious subset of views that
need to be updatable).

Tom Lane 95f20b96d4 Rotate on time boundaries that are sensible per local time rather than GMT. 
Also, avoid truncating the file we just wrote into, which might otherwise
easily happen at DST boundaries.  Ed L. and Tom Lane.

Tom Lane 6da0c439ee Change some of the existing plpgsql regression test cases so that they 
exercise dollar quoting and named function parameters.  AFAICS we had
no tests of either feature before.
 2004-09-20 23:00:12 +00:00
Tom Lane 2f48836b1f Some editorializing on the docs for the dollar-quoting feature: fix 
grammar, don't drop discussions into the middle of unrelated discussions,
etc.

Tom Lane 5b564e5307 Fix some shortcomings in psql's autocommit-off mode concerning detection 
of commands for which a transaction block should not be forced.  Recognize
VACUUM and other PreventTransactionChain commands; handle nested /* .. */
comments correctly; handle multibyte encodings correctly.
Michael Paesold with some kibitzing from Tom Lane.

Tom Lane 768b647ead Now that I look, table 8-1 has some other marginal misstatements in it. 
If we're going to put brackets around optional precision specs in some
entries, we'd better do it in all.

Neil Conway f6279e9ed7 Minor documentation cleanup and improvement. 2004-09-20 00:04:19 +00:00
Tom Lane fa8eb8a726 Add defenses against plpython functions being declared to take or return 
pseudotypes.  Not sure why I neglected to add these checks at the same
time I added them to the other PLs, but it seems I did.

Tom Lane 84c7cef5eb Fix estimate_num_groups to be able to use expression-index statistics 
when there is an expressional index matching a GROUP BY item.

Peter Eisentraut 915351e9c7 Add support for GNU/Hurd and GNU/*BSD. For our purposes, they behave just 
like Linux; we just need to recognize the system types.

Tom Lane a5713ec427 Hashed LEFT JOIN would miss outer tuples with no inner match if the join 
was large enough to be batched and the tuples fell into a batch where
there were no inner tuples at all.  Thanks to Xiaoyu Wang for finding a
test case that exposed this long-standing bug.
 2004-09-17 18:28:53 +00:00
Tom Lane 054b78ba38 Now that xmax and cmin are distinct fields again, we should zero xmax when 
creating a new tuple.  This is just for debugging sanity, though, since
nothing should be paying any attention to xmax when the HEAP_XMAX_INVALID
bit is set.

from James William Pye.

Tom Lane 9f6df6c4a6 Fix oversight: there's no reason for PG_TRY to use sigsetjmp(buf,1) 
since we don't change the signal mask during normal backend operations.
Use sigsetjmp(buf,0) to avoid many unnecessary kernel calls.

Tom Lane 257cccbe5e Add some marginal tweaks to eliminate memory leakages associated with 
subtransactions.  Trivial subxacts (such as a plpgsql exception block
containing no database access) now demonstrably leak zero bytes.
 2004-09-16 20:17:49 +00:00
Tom Lane 86fff990b2 RecentXmin is too recent to use as the cutoff point for accessing 
pg_subtrans --- what we need is the oldest xmin of any snapshot in use
in the current top transaction.  Introduce a new variable TransactionXmin
to play this role.  Fixes intermittent regression failure reported by
Neil Conway.

Tom Lane 8f9f198603 Restructure subtransaction handling to reduce resource consumption, 
as per recent discussions.  Invent SubTransactionIds that are managed like
CommandIds (ie, counter is reset at start of each top transaction), and
use these instead of TransactionIds to keep track of subtransaction status
in those modules that need it.  This means that a subtransaction does not
need an XID unless it actually inserts/modifies rows in the database.
Accordingly, don't assign it an XID nor take a lock on the XID until it
tries to do that.  This saves a lot of overhead for subtransactions that
are only used for error recovery (eg plpgsql exceptions).  Also, arrange
to release a subtransaction's XID lock as soon as the subtransaction
exits, in both the commit and abort cases.  This avoids holding many
unique locks after a long series of subtransactions.  The price is some
additional overhead in XactLockTableWait, but that seems acceptable.
Finally, restructure the state machine in xact.c to have a more orthogonal
set of states for subtransactions.

Neil Conway 42c0d1f3cd Minor doc tweak: mention that function names can be optionally schema- 
qualified.

cosmetic code cleanup at the same time.

Neil Conway d1b0d965b1 Cosmetic PL/PgSQL fix: declare the second parameter plpgsql_dstring_append

Peter Eisentraut adf9a28bb8 Translation update 2004-09-13 20:53:10 +00:00
Tom Lane b2c4071299 Redesign query-snapshot timing so that volatile functions in READ COMMITTED 
mode see a fresh snapshot for each command in the function, rather than
using the latest interactive command's snapshot.  Also, suppress fresh
snapshots as well as CommandCounterIncrement inside STABLE and IMMUTABLE
functions, instead using the snapshot taken for the most closely nested
regular query.  (This behavior is only sane for read-only functions, so
the patch also enforces that such functions contain only SELECT commands.)
As per my proposal of 6-Sep-2004; I note that I floated essentially the
same proposal on 19-Jun-2002, but that discussion tailed off without any
action.  Since 8.0 seems like the right place to be taking possibly
nontrivial backwards compatibility hits, let's get it done now.
