Re: Postgres database : Out of balance problem from the same table

Hi Kevin

Thanks for feedback, I was going to answer your questions and I believe that your questions were going to lead us to the solution due to the fact that one of my seniors discovered that there is a bug on getting the data from master to the backup affecting only this table audmth, which is what you asked below.

Many Thanks

How are you getting the data from the master to the backup? What
does the definition of the audmth table look like (including
indexes)? How many rows are in it? Have you gotten any unusual
messages in the log?

How did you restore from one to the other, exactly? Where on each
machine are you deploying the data? Which port is being used in
each case? How are you starting and stopping the databases? When
you say you still get the difference, do you mean the total is
staying with the machine or following the copy of the database?

What version of PostgreSQL is this? How did you install it?

Since identical databases running identical software don't return
different results for the same query, there is some important fact
you haven't told us yet. Maybe one of the questions I've asked will
draw that out, but it would be best if you took some time to think
about what else might be different that you haven't told us yet.
