Hi, everybody!
I am getting a weird failure, trying to vacuum a table in 7.3 - it says
"ERROR: Index pg_toast_89407_index is not a btree".
Does it ring a bell to anyone? Any ideas what's wrong? Is it my database
screwed up? I just created it today...
I tried dropping and recreating it... and it seems to be working now.
But still, if it all possible, I would appreciate any ideas as to what
it could be that caused this problem in the...

Hello,
Is it normal for plain VACUUM on large table to degrade performance by over
9 times? My database becomes unusable when VACUUM runs. From reading
newsgroups, I thought VACUUM should only slow down by 10% to 15%. Other MVCC
databases like MySQL InnoDB can even VACUUM discretely (runs internally). Is
it my Linux system or is it PostgreSQL?
The database is mostly read-only. There are 133,000 rows and each row is
about 2.5kB in size...

To all,
The facts:
PostgreSQL 7.4.0 running on BSD 5.1 on Dell 2650 with 4GB RAM, 5 SCSI
drives in hardware RAID 0 configuration. Database size with indexes is
currently 122GB. DB size before we completed the vacuum full was 150GB.
We have recently done a major update to a table, f_pageviews, in our
data warehouse. The f_pageviews table contains about 118 million rows.

Any comments on multi-versioning problem:
As far as I understand from PG documentation, *CURRENTLY* VACUUM must be run
regulary, otherwise:
-Q. database will grow as fast as there are many DML going on it, won't it?
-Q. transaction ID may wrap - no doubt here.
-Q. Good news that VACUUM nowdays can run in parallel with other db activity

Hi,
just a few questions on the Vaccum
I run a vacuum analyze on the database every night as part of a
maintenance job.
During the day I have a job that loads 30-70,000 records into two tables
(each 30-70k).
This job runs 2-3 times a day; the first time mainly inserts, the 2nd,
3rd time mostly updates.

Hi ,
I am developing a script that will delete old data from various tables
in a database periodically. The script deletes data from all the tables,
one by one, in single go. I have two options of running vacuum here -
One is to run vacuum analyze each time the table data is deleted, or
another is to run vacuum analyze after the data is deleted from all the
tables. Please note that data has been deleted from all the tables and

Postgresql 7.4.5
The following VACUUMs were run within a couple of minutes of each other completing.
This table concerned is a table that has not been changed in a long time. (a month)
There were open transactions at the time the vacuum was run. These were created by having PHP running with
postgresql. At least that is what I have managed to find so far. and disabling PHP in apache removes them.

Hello!
I have 24/7 production server under high load.
I need to perform vacuum full on several tables to recover disk
space / memory usage frequently ( the server must be online during
vacuum time )
The one trick that i see is to try to vacuum duplicate of
production database ( or just some tables ).
But there are some pitfalls:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
