Babelfish for PostgreSQL provides the capability for PostgreSQL to work with applications written for Microsoft SQL Server. Babelfish understands the SQL Server wire-protocol and T-SQL, the Microsoft SQL Server query and procedural language, so you don’t have to switch database drivers or rewrite all of your application queries.
In our previous attempt of fixing sp_describe_undeclared_parameters related crash, we missed some corner cases where few variables will be left NULL if is_sp_describe_undeclared_parameters is marked as false. Then when we try to access those variables, we get seg fault.
In this commit, we fix it by adding extra check on is_sp_describe_undeclared_parameters.
