Bruce Momjian 0bddf3da81 cleanup 1999-06-03 20:45:08 +00:00
Bruce Momjian a6ed4794a3 SET TRANSACTION ISOLATION LEVEL SERIALIZABLE; 
SET TRANSACTION ISOLATION LEVEL READ COMMITTED;
                                ^^^^ required

Also note that SET TRANSACTION ISOLATION LEVEL change
isolevel for _current_ transaction, in accordance with
standard, not for session (ALTER SESSION is used in Oracle,
but it's not implemented currently).

And I would don't mention SET XACTISOLEVEL TO ...
form at all.

Please update set.sgml - I failed to understand all these

SET TIME ZONE { '<REPLACEABLE CLASS="PARAMETER">

now.


for Vadim
 1999-06-03 20:44:28 +00:00
Bruce Momjian 155b5808ca Thanks for this, but SET TRANSACTION ISOLATION LEVEL 
should be described like SET TIME ZONE: TO is not allowed, as well
as DEFAULT option. There are only two forms:

for Vadim.

Vadim B. Mikheev 5541abee0d 1. Additional fix against ERROR: Child itemid marked as unused 
in CommitTransaction().
2. Changes in GetSnapshotData().

Vadim B. Mikheev f103501286 Unuseful tuple.t_data->t_infomask & HEAP_XMIN_COMMITTED in 
vc_scanheap().

Vadim B. Mikheev fb4f5f7cac Notes in Migration to v6.5 section. 1999-06-03 07:11:50 +00:00
Vadim B. Mikheev 9680a71205 1. MyProc->xid assignment is moved to GetNewTransactionId so newer 
transactions will not assume that MyProc transaction was committed
   before snapshot calculations. With old MyProc->xid assignment
   (in xact.c:StartTransaction()) there was ability to see the same
   row twice (I used gdb for this)!...
2. Assignments of InvalidTransactionId to MyProc->xid and MyProc->xmin
   are moved from xact.c:CommitTransaction() to
   xact.c:RecordTransactionCommit() - this invalidation must be done
   before releasing transaction locks or bad (too high) XmaxRecent value
   might be used by vacuum ("ERROR:  Child itemid marked as unused"
   reported by "Hiroshi Inoue" <Inoue@tpf.co.jp>; once again, gdb
   allowed me reproduce this error).

Thomas G. Lockhart f3d2b2e0c7 Markup changes for v6.5 release. 
Clean out duplicate stuff in odbc.sgml resulting from a faulty patch.

Thomas G. Lockhart 214e8f3292 CGM format from Hannu. Seem to have lost the .ag original :( 1999-06-03 04:20:32 +00:00
Thomas G. Lockhart 3d34943b92 New versions of hardcopy for 6.5 release. 1999-06-03 04:18:58 +00:00
Tom Lane 58d8584eea pg_dump failed on any database containing large objects, 
because it ignored the LOs themselves but failed to ignore the indexes
on the LOs.  How long has this been broken??
 1999-06-03 04:01:16 +00:00
Tom Lane f463c44fc0 Ensure consistent results when FormSortKeys fails to find 
all the expected keys (it was returning uninitialized memory).

Tom Lane 9b3e2dda16 Ooops ... dllist.c can't use Assert() when it is compiled into 
libpq ...

Bruce Momjian e47b93d333 The INET and CIDR types mistakenly compared 198.68.123.0/24 and 
198.68.123.0/27 the same when indexing them.

Thomas G. Lockhart 8593e1ff09 Make sure that only one intro is included in the integrated doc. 
Multiple intros cause trouble since they have some section elements
 (e.g. "y2k.sgml") in common leading to duplicate labels.
Include emacs formatting hints in the intro*.sgml sources.

Bruce Momjian 42a02c441a forgot to attach the patch. :( 
Vince.

Bruce Momjian d2ab04ca73 commented out PgConnection& references for now. May be using them 
later.

Tom Lane 185b427284 Fix some latent bugs in dllist.c (carelessness about setting 
all fields that should be set).  Add a MoveToFront primitive to speed up
one of the hotspots in SearchSysCache.
 1999-05-31 23:48:04 +00:00
Tom Lane 2a44383a2d Clean up memory leaks in LO operations by freeing LO's private 
memory context at transaction commit or abort.
 1999-05-31 22:53:59 +00:00
Tom Lane 81ced1e037 Generate a more specific error message when an operator used 
in an index doesn't have a restriction selectivity estimator.
 1999-05-31 19:32:47 +00:00
Tom Lane cc384fa240 Round up shmem size estimate to 1Kb boundary. 1999-05-31 18:28:52 +00:00
Tom Lane 86482e17bd Correct serious bug in hashtable expansion routine: under the 
right circumstances it would leave old and new bucket headers pointing to
the same list of records.
 1999-05-31 17:01:52 +00:00
Bruce Momjian 7f79496aa5 NT similar file update. 1999-05-31 16:18:53 +00:00
Vadim B. Mikheev 219bb76d61 Release XactLockTable share lock immediately after this lock is acquired 
(no sense to hold it) or we'll be out of lock entries.
Great thanks to Hiroshi Inoue.

Tom Lane ca08ce28e8 Clean up uninitialized-variable warning from egcs. 
(Curious that gcc doesn't complain about this code...).
 1999-05-30 15:32:45 +00:00
Tom Lane 3257b0e592 egcs thinks omitting the return type in a function declaration 
is poor coding style.  I agree.
 1999-05-30 15:22:34 +00:00
Tom Lane d4d297af3c Replace static rcsid[] strings by IDENTIFICATION comments in 
file headers, to conform to established Postgres coding style and avoid
warnings from gcc.
 1999-05-30 15:17:58 +00:00
Tom Lane 6687bcb558 configure.in forgot to do AC_LANG_C to reselect C-based tests 
after checking for presence of C++ compiler.  Odd we hadn't seen any
reports of problems before...
 1999-05-30 00:06:44 +00:00
Tom Lane 6f979c1541 Turns out that configure's test for HPUXMATHLIB didn't work 
when used with egcs --- now it does.
 1999-05-29 16:26:42 +00:00
Vadim B. Mikheev df9e539ea2 1. Run all pg_dump queries in single serializable transaction. 
2. Get rid of locking when updating statistics in vacuum.
3. Use QuerySnapshot in COPY TO and call SetQuerySnashot
   in main tcop loop before FETCH and COPY TO.
