Thanks for the report!
I could reproduce the problem. The cause of error was wrong handling of
parameters given by PL/pgSQL for PL/pgSQL variables and parameters.
They need instantiation with callback routine, and might have InvalidOid
(0) for type oid. I fixed pgsql_fdw for two points:
1) instantiate parameters given by PL/pgSQL with callback function
2) use TEXTOID for type-unknown parameters which are not used in remote
query
Please try HEAD of git.
