Hello
Would you like to advice to use REINDEX DATABASE on regular basis ?
if (yes)
how it should be connected with VACUUM FULL ANALYZE which is run
regularly ? (reindex before vacuum or vacuum before reindex?)
else
haw to determine _when_ to run REINDEX ?
many thanks

If you are doing ordinary VACUUM ANALYZE frequently enough, it
shouldn't be necessary to either VACUUM FULL or REINDEX.
Back in the 7.2 days, there were sorts of update patterns that would
mandate reindexing every so often, as you could get cases where index
pages would be very sparsely populated. That was alleviated in
version 7.3, I believe, and was clearly evident in 7.4.
You know you need to REINDEX if analysis of an index shows that it is
sparsely populated. This generally shows up if you do an analyze on
the table and find an index has more pages than tuples.
But if you run VACUUM reasonably frequently, this shouldn't be
necessary...

I vacuum analyze every hour, however after reindexdb
my (currently) 2.47 GB db is reduced to 2.37 GB,
thus helping both db-wise and freebsd_cache-wise boost performance.
All the above in 7.4.6.
I am not arguing that i have done detailed analysis of the
situation, i'm just saying that i have witnessed a performance gain after
running contrib/reindexdb every month (or so).

That doesn't strike me as being a material improvement, and it comes
at a pretty high cost.
You can get a savings of about 4% of the space, but at the cost of
taking an appreciable outage during which the database is not usable.
I wouldn't expect the 4% savings in space to lead to a particularly
measurable improvement in performance, certainly not one worth the
outage.

The numbers above are just the numbers reported after doing
a live reindex on the spot after deciding to answer to this email.
In the past (when the db was smaller) and for the same version,
i have come across much "striking" numbers,
and much more striking boost gain.
(e.g. a 2+ GB db directory turning to a ~1.5 GB dir).
BTW whats the limit of kern.ipc.shmmax for 32-bit intel?
~ 2^31 = ~ 2 GB.
In those cases i noticed severe boost gain.
(And of course the 1 hour vacuum analyze schedule was always there)

1st not all database is unusable, during the whole reindexdb run,
2nd outage outside office hours is acceptable for those who apply.

I am just saying that the common saying "reindex is not needed for 7.4+"
maybe is not true in all circumstances.

I'm not willing to assume that.
I help support some applications where "outages outside office hours"
are acceptable; I help support some other applications for which
"office hours" are 24 hours per day, 7 days per week, and such an
outage would be deemed decidedly unacceptable.

Let me quote the release notes for 7.4.1:
"Make free space map efficiently reuse empty index pages, and other
free space management improvements
In previous releases, B-tree index pages that were left empty
because of deleted rows could only be reused by rows with index
values similar to the rows originally indexed on that page. In
7.4, VACUUM records empty index pages and allows them to be reused
for any future index rows."
<http://www.postgresql.at/pg/pgsql/doc/html/release-7-4.html;
In versions earlier than 7.4, running a REINDEX periodically was
*essential* if you had update patterns consistent with the (remarkably
common) scenario described above.
This reason to reindex (which was the main reason we required
reindexing when using 7.2) has been resolved and gone away in 7.4.
There may be other factors that could mandate REINDEX; as far as I can
tell, the main such factor that remains would be where a table sees
enormous numbers of updates but is not VACUUMed often enough.
_That_ scenario isn't consistent with what you describe, as it would
be expected to involve a whole lot more than 4% growth in the size of
the database.

I think the case that 7.4 resolved is where you have a
continually-moving window of index values; for example, an index on a
timestamp column in a table where you delete entries older than 30 days.
Before 7.4, index pages for timestamps older than 30 days would become
empty and then just sit there, with no other way to reclaim them than
REINDEX.
The case that isn't resolved yet is where you have a usage pattern that
causes a lot of index pages to become mostly but not entirely empty.
For example, your entries are timestamps, and you have a cleanup process
that removes just 99 out of every 100 successive entries. This'll leave
you with just a couple of index entries per page, which might not be
infinite bloat but it's surely not too efficient.

I'll try to postpone the next reindexdb at the end of august,
and get some numbers then.
However the big difference in performance as i told was near the 2GB
"threshold", and at *that* point (and maybe for different reasons)
performance gain was remarkable.

Well, today i run reindexdb and i noticed a decrease in database size,
from 2890148K to 2527552K, about
12.54% decrease in size.
However i have not an estimation of the distribution
of the SQL commands (INSERT,UPDATE,DELETE) over August.
I am running 7.4.6.

Hi,
It would be so nice to use REINDEX DATABASE command without name, for the
current database.
Now the command is useless when a database schema script refers just itself,
and the database name is not establish. I have to use REINDEX TABLE name
instead searching all the database tables.
What is your opinion ?

Sabin

<path to your db sources>/contrib/reindexdb/reindexdb -a
reindexes everything.
Also your script would do a
