Any idea

Hi all,
I moved a few clusters from 8.4 to 9.0 since I required the new way of
authenticating against LDAP (or, in my case, AD). Now, I found the new
database version introduced permissions on large object, so my
application, in order to share large object across a group, require a
bit of change.

Tomáš and Tony,
thank you.
Have you done some basic monitoring? This typically happens when the
machine does a lot of I/O (swapping, checkpoints, ...) - not sure how this
is logged.
This is dedicated server, used only for PostgreSql.
I filtered windows event logs near this time (12:16) .

I don't know what happened the other day. The query updating the flag

I must have made the test duration too short, so that it was only appearances.
whatever, it works. thanks.

Hi,
LDAP is often used to do a centralized user and role management in an
enterprise environment. PostgreSQL offers different
authentication methods, like LDAP, SSPI, GSSAPI or SSL. However, for any of
these methods the user must already exist in the
database, before the authentication can be

As you asked, I measured the time required to read all documents.
I think your log files, and the description of your issue provide at
least a decent idea of what is probably happening. Unfortunately
without being able to observe the server when it happens, I think you
are going to have limited success tracking this down.

Perhaps you can create a trigger that monitors for the insertion of an

Hi Chris,
I do have a question though. Does your application allow for creating

Yes, filters on both sides can be set and they can

All that can be done just by clicking buttons and labels in the browser. There
