Magnus Hagander c979a1fefa Prevent shutdown in normal mode if online backup is running, and 
have pg_ctl warn about this.

Cancel running online backups (by renaming the backup_label file,
thus rendering the backup useless) when shutting down in fast mode.

Magnus Hagander 3bb6d101c4 Add link to major version release notes at the top of the minor 
version ones, to make it clear to users just browsing the notes
that there are a lot more changes available from whatever version
they are at than what's in the minor version release notes.

Tom Lane 8472bf7a73 Allow float8, int8, and related datatypes to be passed by value on machines 
where Datum is 8 bytes wide.  Since this will break old-style C functions
(those still using version 0 calling convention) that have arguments or
results of these types, provide a configure option to disable it and retain
the old pass-by-reference behavior.  Likewise, provide a configure option
to disable the recently-committed float4 pass-by-value change.

Zoltan Boszormenyi, plus configurability stuff by me.

Tom Lane 87a2f050a9 Cause EXPLAIN's VERBOSE option to print the target list (output column list) 
of each plan node, instead of its former behavior of dumping the internal
representation of the plan tree.  The latter display is still available for
those who really want it (see debug_print_plan), but uses for it are certainly
few and and far between.  Per discussion.

This patch also removes the explain_pretty_print GUC, which is obsoleted
by the change.

Tom Lane 9b5c8d45f6 Push index operator lossiness determination down to GIST/GIN opclass 
"consistent" functions, and remove pg_amop.opreqcheck, as per recent
discussion.  The main immediate benefit of this is that we no longer need
8.3's ugly hack of requiring @@@ rather than @@ to test weight-using tsquery
searches on GIN indexes.  In future it should be possible to optimize some
other queries better than is done now, by detecting at runtime whether the
index match is exact or not.

Tom Lane, after an idea of Heikki's, and with some help from Teodor.

 2008-04-14 13:33:53 +00:00
Tom Lane 24558da14a Phase 2 of project to make index operator lossiness be determined at runtime 
instead of plan time.  Extend the amgettuple API so that the index AM returns
a boolean indicating whether the indexquals need to be rechecked, and make
that rechecking happen in nodeIndexscan.c (currently the only place where
it's expected to be needed; other callers of index_getnext are just erroring
out for now).  For the moment, GIN and GIST have stub logic that just always
sets the recheck flag to TRUE --- I'm hoping to get Teodor to handle pushing
that control down to the opclass consistent() functions.  The planner no
longer pays any attention to amopreqcheck, and that catalog column will go
away in due course.
 2008-04-13 19:18:14 +00:00
Tom Lane c22ed3d523 Turn the -i/--ignore-version options of pg_dump and pg_dumpall into no-ops: 
the server version check is now always enforced.  Relax the version check to
allow a server that is of pg_dump's own major version but a later minor
version; this is the only case that -i was at all safe to use in.

pg_restore already enforced only a very weak version check, so this is
really just a documentation change for it.

Per discussion.

Bruce Momjian a464dc07fe Update URLs for dead space map. 2008-04-11 19:14:57 +00:00
Tom Lane 4e82a95476 Replace "amgetmulti" AM functions with "amgetbitmap", in which the whole 
indexscan always occurs in one call, and the results are returned in a
TIDBitmap instead of a limited-size array of TIDs.  This should improve
speed a little by reducing AM entry/exit overhead, and it is necessary
infrastructure if we are ever to support bitmap indexes.

In an only slightly related change, add support for TIDBitmaps to preserve
(somewhat lossily) the knowledge that particular TIDs reported by an index
need to have their quals rechecked when the heap is visited.  This facility
is not really used yet; we'll need to extend the forced-recheck feature to
plain indexscans before it's useful, and that hasn't been coded yet.
The intent is to use it to clean up 8.3's horrid @@@ kluge for text search
with weighted queries.  There might be other uses in future, but that one
alone is sufficient reason.

Heikki Linnakangas, with some adjustments by me.

Tom Lane a0fad9762a Re-implement division for numeric values using the traditional "schoolbook" 
algorithm.  This is a good deal slower than our old roundoff-error-prone
code for long inputs, so we keep the old code for use in the transcendental
functions, where everything is approximate anyway.  Also create a
user-accessible function div(numeric, numeric) to provide access to the
exact result of trunc(x/y) --- since the regular numeric / operator will
round off its result, simply computing that expression in SQL doesn't
reliably give the desired answer.  This fixes bug #3387 and various related
corner cases, and improves the usefulness of PG for high-precision integer
arithmetic.

 2008-04-01 03:51:09 +00:00
Tom Lane d5466e38f0 Add SPI-level support for executing SQL commands with one-time-use plans, 
that is commands that have out-of-line parameters but the plan is prepared
assuming that the parameter values are constants.  This is needed for the
plpgsql EXECUTE USING patch, but will probably have use elsewhere.

This commit includes the SPI functions and documentation, but no callers
nor regression tests.  The upcoming EXECUTE USING patch will provide
regression-test coverage.  I thought committing this separately made
sense since it's logically a distinct feature.

Tom Lane 3405f2b925 Use error message wordings for permissions checks on .pgpass and SSL private 
key files that are similar to the one for the postmaster's data directory
permissions check.  (I chose to standardize on that one since it's the most
heavily used and presumably best-wordsmithed by now.)  Also eliminate explicit
tests on file ownership in these places, since the ensuing read attempt must
fail anyway if it's wrong, and there seems no value in issuing the same error
message for distinct problems.  (But I left in the explicit ownership test in
postmaster.c, since it had its own error message anyway.)  Also be more
specific in the documentation's descriptions of these checks.  Per a gripe
from Kevin Hunter.

Neil Conway c111a7211f Update documentation for recent DTrace changes. Patch from Robert Lor. 2008-03-25 22:50:27 +00:00
Tom Lane 220db7ccd8 Simplify and standardize conversions between TEXT datums and ordinary C 
strings.  This patch introduces four support functions cstring_to_text,
cstring_to_text_with_len, text_to_cstring, and text_to_cstring_buffer, and
two macros CStringGetTextDatum and TextDatumGetCString.  A number of
existing macros that provided variants on these themes were removed.

Most of the places that need to make such conversions now require just one
function or macro call, in place of the multiple notational layers that used
to be needed.  There are no longer any direct calls of textout or textin,
and we got most of the places that were using handmade conversions via
memcpy (there may be a few still lurking, though).

This commit doesn't make any serious effort to eliminate transient memory
leaks caused by detoasting toasted text objects before they reach
text_to_cstring.  We changed PG_GETARG_TEXT_P to PG_GETARG_TEXT_PP in a few
places where it was easy, but much more could be done.

Tom Lane 05fc744b96 Add a new ereport auxiliary function errdetail_log(), which works the same as 
errdetail except the string goes only to the server log, replacing the normal
errdetail there.  This provides a reasonably clean way of dealing with error
details that are too security-sensitive or too bulky to send to the client.

This commit just adds the infrastructure --- actual uses to follow.

except that it returns the string 'NULL', rather than a SQL null, when called
with a null argument.  This is often a much more useful behavior for
constructing dynamic queries.  Add more discussion to the documentation

Tom Lane 6b0706ac33 Arrange for an explicit cast applied to an ARRAY[] constructor to be applied 
directly to all the member expressions, instead of the previous implementation
where the ARRAY[] constructor would infer a common element type and then we'd
coerce the finished array after the fact.  This has a number of benefits,
one being that we can allow an empty ARRAY[] construct so long as its
element type is specified by such a cast.

Bruce Momjian 2f2b58d642 Spit items: 
* Experiment with multi-threaded backend better I/O utilization

  This would allow a single query to make use of multiple I/O channels
  simultaneously.  One idea is to create a background reader that can
  pre-fetch sequential and index scan pages needed by other backends.
  This could be expanded to allow concurrent reads from multiple devices
  in a partitioned table.

* Experiment with multi-threaded backend better CPU utilization

  This would allow several CPUs to be used for a single query, such as
  for sorting or query execution.

Tom Lane 033eb1581b Fix LISTEN/NOTIFY race condition reported by Laurent Birtz, by postponing 
pg_listener modifications commanded by LISTEN and UNLISTEN until the end
of the current transaction.  This allows us to hold the ExclusiveLock on
pg_listener until after commit, with no greater risk of deadlock than there
was before.  Aside from fixing the race condition, this gets rid of a
truly ugly kludge that was there before, namely having to ignore
HeapTupleBeingUpdated failures during NOTIFY.  There is a small potential
incompatibility, which is that if a transaction issues LISTEN or UNLISTEN
and then looks into pg_listener before committing, it won't see any resulting
row insertion or deletion, where before it would have.  It seems unlikely
that anyone would be depending on that, though.

This patch also disallows LISTEN and UNLISTEN inside a prepared transaction.
That case had some pretty undesirable properties already, such as possibly
allowing pg_listener entries to be made for PIDs no longer present, so
disallowing it seems like a better idea than trying to maintain the behavior.

  For large table adjustments during VACUUM FULL, it is faster to cluster
