I am not using odbc at all but as I can see from Erlang ODBC doc
Erlang ODBC application is designed using the version 3.0 of the
ODBC-standard
and according to this page ODBC Connection pooling
As of release 2.0.0 of unixODBC the driver supports connection
pooling. This is a method to increase the connection speed of drivers,
but leaving connection's open and reusing them. This document
discusses how to implement connection pooling in unixODBC, and also
what you should be aware of before doing it.
So it means that Erlang ODBC support connection pooling
but I feel that you cant accept any options of pool directly from the Erlang application
