The maintainer of this module has not implemented the connection pool 
yet. It was no activity for quite some time of postgres module,but now

is the same problem as in ser. It is the same module, we just fixed some 
warnings and a few bugs reported by users.

It is limited to startup value, it does not fork additional children if 
needed. The maximum number of children is 32. By default it is 8.
