Status of ODBC

First I would like to thank everybody that answered.

All the infrastructure was set up correctly (odbcserver, etc)
I discovered that the problem was my poor Erlang knowledge, I was doing:
Ref = odbc:connect("DSN=PostgreSQL;UID=XXX;PWD=XXX",[{scrollable_cursors, 

odbc:sql_query(Ref,"select * from t1").

The "Ref =" should have been "{ok, Ref} ="

This was causing odbcserver to shutdown (not a crash, a normal exit).

If nobody opposes I would like to document on the wiki my experience in 
putting ODBC to work on Linux/PostgreSQL (including most of the issues raised 
by all the people that answered my previous email).

BTW, I will be making changes to odbcserver and the odbc module to include 
support for metadata, if anyone is interested in these changes, I will be 
more than happy to share them.
