RESOLVED: odbc driver manager and postgresql odbc driver

Success. Thanks Josh for the no-nonsense reply.

Basically, I didn't know the location of the appropriate libraries, and I
was confused about all the options available.

I now have the packages "unixodbc-bin" and "odbc-postgresql" installed.
The files /etc/odbc.in and /etc/odbcinst.ini are as follows:

[postgreodbc]
Description     = PostgreSQL ODBC driver
Driver          = /usr/lib/odbc/psqlodbc.so
Setup           = /usr/lib/odbc/libodbcpsqlS.so
Debug           = 0
CommLog         = 1
UsageCount      = 2


[gfsDB]
Description           = PostgreSQL ODBC
Driver                = postgreodbc
Trace                 = No
TraceFile             =
Database                = mydatabase
Servername              = localhost
UserName                = postgres
Password                =
Port                    = 5432
Protocol                = 7.0
ReadOnly                = No
RowVersioning           = No
ShowSystemTables        = No
ShowOidColumn           = No
FakeOidIndex            = No
ConnSettings            =



A final question then, part of the original confusion. Where is the file
"/usr/lib/odbc/libodbcpsqlS.so" from? It doesn't seem to be from the
odbc-postgresql package:

ricardd@octopus:~$ dpkg -L odbc-postgresql
/.
