Обсуждение: Libpq in C Language Function

Hi,

Is it possible to connect to another database from within a database.
The 2 databases will probably not be on the same computer.

Is it possible to create a C LANGUAGE function that connects to
another database using libpq? I have tried this but after calling
PQconnectedb the status returned by PQstatus is CONNECTION_BAD.

It sounds like you want dblink.
