Subject: [ADMIN] Query performance difference

Hello,
I have a question regarding query performance from two pgsql applications. PGadmin III 1.8 and Navicat for postgresql 8. Both connected to same server on local machine 8.3 and runs a same query for appox. 1,60,000 rows with one min, one max and addition of the min and max values on two tables joined on an integer column gives different query execution times with noticible difference. PGAdmin gives 9350ms and Navicat gives 2110ms. Why? What will be the difference?
Is it in their query execution methods, with/without indexes etc?.
Thanks

CPK
