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.

a83c71eb24 Clean up rather sloppy fix in HEAD for the ancient bug that CREATE CONVERSION
didn't create a dependency from the new conversion to its schema.  Back-patch
to all supported releases.

0d5065781d Update logging of prepare/execute syntax, per comments from Guillaume Smet. 2006-08-30 18:22:02 +00:00
3a6e2ff08a Fix things so that fopen's, not only open's, pass FILE_SHARE_DELETE
and other special flags on Windows.  May fix intermittent 'Permission
denied' errors.  Magnus Hagander

f6d7ef08a7 Dept. of second thoughts: if query fails part way through, shut down
the pager before reporting the error.

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.

7c5ac5ce22 Separate prepared statement and bind parameters with comma.
Fix printing of NULL bind parameters, use "NULL".

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.

b681bfdd59 Fix BUG #2594: Gin Indexes cause server to crash when it builds on empty table 2006-08-29 14:05:44 +00:00
cda6d0a8d3 Second try committing the path changes. 2006-08-29 13:23:27 +00:00

b1710339ba Fixed parser and library to allow empty database names.
Streamlined connection name parsing.

f443258d4f Only call log_after_parse() if necessary. 2006-08-29 02:32:41 +00:00
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().
2006-08-28 14:32:41 +00:00
88b8110443 Turn autovacuum on by default. (stats_row_level is also on by default.)
Threshold and scale factor are cut in half for more aggressive behavior.

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.

7a2fe85b03 Add some notes about why it's not a bug that RI_FKey_check calls
HeapTupleSatisfiesItself without doing LockBuffer first.  This code
is a bit fragile, but AFAICS it's not actually broken.
2006-08-27 21:41:21 +00:00
e06fda0a8b Add a function GetLockConflicts() to lock.c to report xacts holding
locks that would conflict with a specified lock request, without
actually trying to get that lock.  Use this instead of the former ad hoc
method of doing the first wait step in CREATE INDEX CONCURRENTLY.
Fixes problem with undetected deadlock and in many cases will allow the
index creation to proceed sooner than it otherwise could've.  Per
discussion with Greg Stark.
2006-08-27 19:14:34 +00:00
ca1fd0ea5b Move xact.c's partial support for Lists of TransactionIds into pg_list.h.
Needed because lock.c is now going to use the same type of list.

e093dcdd28 Add the ability to create indexes 'concurrently', that is, without
blocking concurrent writes to the table.  Greg Stark, with a little help
from Tom Lane.

f836c2e37e Add some debug logging code to AllocateFile's failure path to log the
specific Windows error code (GetLastError).  This is a hopefully temporary
hack to try to diagnose rare failures.  Magnus Hagander

08ae5edc5c Optimize the case where a btree indexscan has current and mark positions
on the same index page; we can avoid data copying as well as buffer refcount
manipulations in this common case.  Makes for a small but noticeable
improvement in mergejoin speed.

a6558b068d Somehow my version compiled but the change didn't make it to CVS. 2006-08-23 13:57:27 +00:00
02c3cdbaad Argh, forgot the new file yet again. 2006-08-23 12:51:26 +00:00
9bade3ff84 Replaced double-quote-fix with a hopefully better version.
Use initializer string length as size for character strings.
Added ecpg_config.h file that is created via configure.

54f5527606 Descriptor values were quoted twice.
Fixed some regression test problems.

a3132359fd In new "invalid byte sequence" error hint, call it "error", not
"failure".

suggesting review of client_encoding.

entirely on older Windows platforms without the needed library function.

d7c310c1fa Minor code rearrangement to save a few cycles in RI_FKey_check when
the subject tuple is already deleted: we need not open the pk_rel
until after we check that.

35af5422f6 Make the server track an 'XID epoch', that is, maintain higher-order bits
of the transaction ID counter.  Nothing is done with the epoch except to
store it in checkpoint records, but this provides a foundation with which
add-on code can pretend that XIDs never wrap around.  This is a severely
trimmed and rewritten version of the xxid patch submitted by Marko Kreen.
Per discussion, the epoch counter seems the only part of xxid that really
needs to be in the core server.
