Hi,there,
I hope it helps;
1. postgres by default allows 16 sessiones(if I don't remember wrong)
at same time. You can change the setting according to the doccument.
open too many sessiones at same time will more or less affect the
performance.
2. I believe that using Pg module will be easier than DBI.
