[PATCH] Allow catalogname (database) and procname （no under public schema) enumeration with SQLProcedures

hello！

The attached patch fixed  SQLProcedures two bug:

1.  make enumeration of databases (catalogs in ODBC speak) work.

2.  make enumeration of procedurename (procname  in ODBC speak) work.

Step:

   1.  login postgres

   2.  create schem named  schem1 

   3.  set search_path TO schem1

   4.  create procedure named genre_insert_data

   5.  with odbc application（retcode =  SQLProcedures (hstmt, NULL, 0, NULL, 0, (SQLCHAR *)"genre_insert_data", strlen("genre_insert_data"));）to get the genre_insert_data(step 4)

   6.  the result is empty.
