I even tried out the recommended upgrade technique also. That is, installed
new version (9.0.3 in this case) of PostgreSQL in a different directory in
the same machine and used pg_dump of this latest version to access the old
database (running 8.2.3 in this case) to take a dump and then imported into
9.0.3. Still I'm facing *exactly* the same set of errors after importing (as
I was getting before).
ERROR: constraint "xxxx" for relation "xxxx" already exist
There are 260 occurrences of this type of error.
How do I resolve/fix this problem at this stage? Since this issue we're
facing is with our Production database dump, timely suggestions/advice/help
to resolve this are highly appreciated.
