SQLTables() doesn't support enumeration

I'm using ODBCTest 3.510.3513.0 and psqlodbc 07.03.0200 on Windows 2000 
with PostgreSQL 7.3.2 on SuSE Linux 8.2.
From the SQLTables() section in the ODBC Programmer's Reference: "To 
support enumeration ... the following special semantics are defined for the 
CatalogName, SchemaName, TableName, and TableType arguments of SQLTables:
"If SchemaName is SQL_ALL_SCHEMAS and CatalogName and TableName are empty 
strings, the result set contains a list of valid schemas for the data 
source.  (All columns except the TABLE_SCHEM column contain NULLs.) ..."
Instead of getting the expected list, I get a list of tables.
