Thanks for all your responses.
Sorry for late response
Earlier we used Postgres8.3.10 with Desktop computer (as server) and configuration of the system (I2 core with 4GB RAM) and also the application was slow i dint change any postgres config settings.
May be because of low config We thought the aplication is slow so we opted to go for higher configuration server(with RAID 1) which i mentioned earlier.
I thought the application will go fast but unfortunately there is no improvement so i tried to change the postgres config settings and trying to tune my queries wherever possible but still i was not able to..........improve the performance..
So will it helpful if we try GIST or GIN for integer array[] colum (source_detail) with enable_seqscan=off and default_statistics_target=1000?

No doubt about that, querying tables using conditions on array columns is
not the best direction in most cases, especially when those tables are
huge.
Still, the interesting part here is that the OP claims this worked just
fine in the older version and after an upgrade the performance suddenly
dropped. This could be caused by many things, and we're just guessing
because we don't have any plans from the old version.

Not really, Mohamed always said he has 9.0.3, Marcus Engene wrote about problems after the migration from 8.x to 9.x. Or did I miss something here?
