Q: ODBC- and PostgreSQL-datatypes difference?

Hi all,

I've posted some time ago about my experiences concerning connecting from
a Mac-client via OpenLink to a Linux-server with PostgreSQL. Now I'm able
to connect, but the datatypes ODBC gives back to the client aren't all as
I supposed they would be.

A small table with some datatypes/results:

PostgreSQL- Length ODBC-datatype
datatype
bool 1 SQL_CHAR
date 10 SQL_CHAR
time 16 SQL_CHAR
timestamp 30 SQL_CHAR
int2 2 SQL_SMALLINT
int4 4 SQL_INTEGER
int8 8 SQL_CHAR
float4 4 SQL_REAL
float8 8 SQL_DOUBLE
char 16 SQL_CHAR
varchar 255 SQL_VARCHAR
text 8000 SQL_LONGVARCHAR

Is this normal behaviour, or is this due to the OpenLink-software which
has a database-agent highly possible based on Postgres95, or is this
something different?

I suppose PostgreSQL 'talks' with ODBC-clients via an embedded
ODBC-interface. If so, how can I test this interface and check if there
are some problems?

PostgreSQL: 6.5.2
Linux: RH 6.0

Thanks,
Jelle.
