You seem to be trying to use the libpq client from inside the backend.
This is entirely inappropriate. If you need to run general-purpose SQL
queries you can use SPI, but code that is doing that probably does not
belong in /parser. Just about anything that makes sense to do during
parse analysis should be adequately supported by the system catalog
cache routines.
