Thanks Laurenz,
Now I need to do 2 things.
1. Correct my application to catch errors and do either Rollback or commit. This part is running smoothly from all other computers, so far. Nevertheless I'll check that for any missing catch.2. Find the faulty entry and do rectify.
For the second part, how to identify that culprit query? Seems this has happened a few days back. At that time, we had some power issues that made network to fail.
To proceed, we need to find the culprit query? How? Where? No idea what was the pid then, as all computers were shut down every night.
Any possibilities? steps?
Happiness Always

You would have to improve the code quality of the application, which does not seem
to do correct error handling or transaction management.
That error means that the *previous* statement (or one of the statements earlier in
the same database transaction) has caused an error. In PostgreSQL, that means that
the transaction is aborted, and the following statements until the end of the
transaction will receive the error you experience.
So one of the following must be the case:
- the previous statement caused an error, but you didn't detect or handle that
- the previous transaction run on the same database connection caused an error,
but you forgot to run ROLLBACK

If the query caused an error, and you left "log_min_messages" at the
default setting, the error and the statement that caused it should
be in the PostgreSQL log.
