dfc6649c4d Add Win32 versions of unlink and rename --- loop until success. 2003-04-22 02:18:09 +00:00

5ed27e35f3 Another round of protocol changes. Backend-to-frontend messages now all 
have length words.  COPY OUT reimplemented per new protocol: it doesn't
need \. anymore, thank goodness.  COPY BINARY to/from frontend works,
at least as far as the backend is concerned --- libpq's PQgetline API
is not up to snuff, and will have to be replaced with something that is
null-safe.  libpq uses message length words for performance improvement
(no cycles wasted rescanning long messages), but not yet for error
recovery.

1dc3a62ec7 stddev() and variance() should return NULL when there is just one input 
value, per recent discussion on pgsql-general.

f9ba0a7fe5 Apple's assembler likes the inlined TAS syntax too, so no reason to 
maintain a separate out-of-line version of PPC tas() anymore.
Also fix S_UNLOCK for __powerpc64__ platforms.

b40bc9eac6 Avoid O(N^2) behavior with lots of deferred triggers by making 
deferredTriggerInvokeEvents only scan events added since it last ran.

c3b7d2d522 Allow \r and \r\n termination for COPY files. 
Output \r\n termination on Win32.

Disallow literal carriage return as a data value,
backslash-carriage-return and \r still allowed.

Doc changes already committed.

cb7fb3ca95 First phase of FE/BE protocol modifications: new StartupPacket layout 
with variable-width fields.  No more truncation of long user names.
Also, libpq can now send its environment-variable-driven SET commands
as part of the startup packet, saving round trips to server.

31845dd363 Fix abstime-to-time cast function, which has had broken implementation 
since 7.2, per bug #947.  Turns out it had wrong volatility label, too.
Can't force initdb in 7.3 branch, but fix anyway for future installs.

5ab15591d9 eqjoinsel's logic for case where MCV lists are not present should 
account for NULLs; in hindsight this is obvious since the code for
the MCV-lists case would reduce to this when there are zero entries
in both lists.  Per example from Alec Mitchell.

da2060e5fd Remove premature attempt to constant-fold type coercion expressions. 
While usually safe, this fails if the coercion function needs the
query snapshot to be set already.  Per example from Nigel Andrews.

730840c9b6 First phase of work on array improvements. ARRAY[x,y,z] constructor 
expressions, ARRAY(sub-SELECT) expressions, some array functions.
Polymorphic functions using ANYARRAY/ANYELEMENT argument and return
types.  Some regression tests in place, documentation is lacking.
Joe Conway, with some kibitzing from Tom Lane.

cd203f3395 Avoid primary key lookup (and lock) if foreign key does not change 
on UPDATE.

This get's rid of the long standing annoyance that updating a row
that has foreign keys locks all the referenced rows even if the
foreign key values do not change.

The trick is to actually do a check identical to NO ACTION after an
eventually done UPDATE in the SET DEFAULT case. Since a SET DEFAULT
operation should have moved referencing rows to a new "home", a following
NO ACTION check can only fail if the column defaults of the referencing
table resulted in the key we actually deleted. Thanks to Stephan.

a385186ff7 Remove zero_damaged_pages from postgresql.conf.sample; the only way to 
find out about it is to read the documentation that tells you how
dangerous it is.  Add default_transaction_read_only to documentation;
seems to have been overlooked in patch that added read-only transactions.
Clean up check_guc comparison script, which has been suffering bit rot.
