Using Which Driver

Dear all,

 

I had installed Postgresql 8.0.3 and installed unixODBC 2.2.11 under Redhat Linux 9.0. And, I found that unixODBC provides

 

                       libodbcpsql.so.2.0.0

                       libodbcpsqlS.so.1.0.0.

 

From www.postgresql.org web site, I found the ODBC Driver

 

                       psqlodbc.so

 

which is compiled and installed from psqlodbc-08.00.0102.tar.gz source package.

 

Would you please tell me the detail on which driver should be used?

 

Thank you very much!

 

Kathy
