sqlparser-rs fails to parse valid PostgreSQL CREATE FUNCTION statements that specify both a library path and symbol name, e.g.:
CREATE FUNCTION cas_in(input cstring)
RETURNS cas
IMMUTABLE PARALLEL SAFE
LANGUAGE c
AS 'MODULE_PATHNAME', 'cas_in_wrapper';
ParserError("Expected: end of statement, found: ,")
I will make a PR adding support for this later after I am finished with #2092
