Dynamic linking issue using the embedded Postgres

[georgelemon]

Understand how to passL path to the libpq.dylib so that the db_connector can find it when using the embedded Postgres.

For now one of the best solution is to use push/pop dynlib pragmas around the code that uses the db_connector to ensure it can find the correct version of libpq.
