Postgres connection problems

Hello,

A week ago I was having problems connecting to a local postgres server. Eventually the problem was solved substituting the driver from "PostgreSQL" to "PostgreSQL UNICODE".

Somehow i'm still not being able to make querys, and the error message show the following:

{0}
0. System.Data.Odbc.OdbcException: ERROR [08001] connction string lacks some options
at System.Data.Odbc.OdbcConnection.HandleError(OdbcHandle hrHandle, RetCode retcode)
at System.Data.Odbc.OdbcConnectionHandle..ctor(OdbcConnection connection, OdbcConnectionString constr, OdbcEnvironmentHandle environmentHandle)

at System.Data.Odbc.OdbcConnection.Open()
at SlingshotDB.GHODBC_QUERY.SolveInstance(IGH_DataAccess DA)

Can anyone tell me what i'm missing?

The connection string I'm trying to use is:

"

Driver={PostgreSQL UNICODE}; Server=localhost; Port=5432; Uid=postgres; Pwd=passwordx; commandtimeout=20; Timeout=5"

Tks,

Pedro.
