I have developed one function in my PostgreSQL database. It was taking 12-15 seconds to execute.

Now I have restored a new PostgreSQL 9.0 dump using following command:

pg_restore -hx.x.x.x -p5432 -d xxx -Ux -Fc -v </path/pgbackup.backup

but on this newly restored database it takes 2 minutes to execute same function.

Please give me possible way to sort out this problem.

How did you take the backup? Are indexes also recreated? Also, what does your function do? Is there a part you suspect being slow (like a select from a table or the like)? – dezso Sep 4 '13 at 8:09
Run ANALYZE and try again. – MatheusOl Sep 5 '13 at 1:03
Please post EXPLAIN ANALYZE output so we can see the query plan used. – Chris Travers Nov 13 '13 at 6:39
