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
