------------------------------------------------

The problem is that in some situations postgresql doesn't store the data it
receives. So, for example, if I make a normal INSERT statement the row supposed
to appear in the database isn't there. This has happened only in situation
where there are at least 20 tables in the database. The database files are
not corrupted. I made a dump of the database and moved the database to
another system with clean postgresql installation and the same happened
trying to insert to the table.

There was one common thing to all the situations I was unable to insert.
They were made using postgresql library of php3 (3.0.9). There were no
error messages or anything but the data just didn't appear in the db.
I solved this problem quick & dirty way by executing psql from the php
script with the statement as a parameter of it. It worked well but now
I have one table that it doesn't work with. The effect is the same as
with php. Everything seems to be fine but the data isn't there.

I run postmaster in debug mode in one console to see if there was something
worth seeing. The output of the debug was exactly the same in cases where
the data disappeared and when it got stored in the db. No error messages.

The problem has been at least in versions 6.3, 6.4 & 6.5.

Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
