You would use the SPI interface to query database tables from a C function: https://www.postgresql.org/docs/current/static/spi.html If you don't feel like reinventing the wheel, there are tricks how to do that with oracle_fdw. You could create an Oracle table with a BEFORE INSERT trigger that executes the procedure. See https://stackoverflow.com/a/46360383/6464308 Yours, Laurenz Albe
