Thank you for the reply.

It has nothing to do with programming. I was trying to back up the 8.1 database (using pg_dump) which had exceeded 2Gig limit according to a response. When I tried to restore it using pg_restore to a 9.0 database, it complained about custom archiver error and corruption and the whole backup stopped.
Â
One response told me to try backing up 8.1 database usingÂ9.0 pg_dump and restore it to 9.0 database using 9.0 pg_restore. Another option, I can think of, is to back up each table one at time and restore it one by one. This way the 2G limit will never come up during the backup. However, it requires a lot of works.
Â
Any suggestion?
Thanks,
Thanks,

Hi.
It is sometimes hard to tune complicated queries. Maybe add new
attribute to functions returning boolean - selectivity, defining how
big is percent of rows for which the function returns true.
