Description:
https://www.postgresql.org/docs/16/libpq-exec.html#LIBPQ-PQRESULTSTATUS
Existing text:
If the result status is PGRES_TUPLES_OK, PGRES_SINGLE_TUPLE, or
PGRES_TUPLES_CHUNK, then the functions described below can be used to
retrieve the rows returned by the query. Note that a SELECT command that
happens to retrieve zero rows still shows PGRES_TUPLES_OK. PGRES_COMMAND_OK
is for commands that can never return rows (INSERT or UPDATE without a
RETURNING clause, etc.). A response of PGRES_EMPTY_QUERY might indicate a
bug in the client software.
Add:
A successful call to a procedure with OUT parameters will set
PGRES_TUPLES_OK and return one row with the functions described below.
