Summary: Incorrect info for varchar(255), text columns

Initial Comment:
PostgreSQL ANSI ODBC driver 8.04.01 returns incorrect info for
SQLColAttribute SQL_DESC_TYPE and/or SQL_DESC_OCTET_LENGTH

Example,
create table test_varchar(col1 varchar(20), col2 varchar(255), col3 text);

I get the following information from SQLColAttribute:
column SQL_DESC_TYPE SQL_DESC_OCTET_LENGTH
col1 SQL_VARCHAR 20
col2 SQL_LONGVARCHAR 255
col3 SQL_LONGVARCHAR 8190

col1 info is correct.
col2 SQL_DESC_TYPE should be SQL_VARCHAR not SQL_LONGVARCHAR.
col3 SQL_DESC_OCTET_LENGTH should be something large such as 2147483647 (2**31 -1)

Attached is screenshot of the Firebird vs PostgreSQL ODBC driver results for the test table above (MS SQL Server ODBC driver returns the same info as the Firebird ODBC driver)
