[BUGS] BUG #5694: Postgres ODBC SQLTables is not working correctly

Hi folks

This request popped up on the -bugs list, and hasn't seen any response.
I don't really do/know ODBC, but it looks like a reasonable concern, so
I thought I'd pass it on in in case there's nobody equipped to deal with
it reading -bugs.

Original message follows.

PostgreSQL version: 8.3.4
Operating system: Windows
Description: Postgres ODBC SQLTables is not working correctly
Details:

Hi,

I'm using PostgreSQL ODBC Unicode (version 8.01.02.00) to connect to a
PostgreSQL server (version 8.3.4).

Following ODBC specification, when ODBC SQLTables is called with
- SchemaName is SQL_ALL_SCHEMAS
- 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.)
http://msdn.microsoft.com/en-us/library/ms711831%28VS.85%29.aspx

But PostgreSQL ODBC returns still the list of tables. As result, we get a
list of duplicated schemas, as many times as the number of the tables in the
schema.

Thanks,
Xiaohui XUE
