I have tried to send to pgsql-general twice, each time it returns error: "Relay access denied (state 14)." Will try to post to pgsql-odbc.

Thank you!

This question would be more appropriate for pgsql-general or maybe
pgsql-odbc, since it is not a question about the development of
PostgreSQL.

character varying and text are different types, but there's no real
difference between them.  I can't speak to what the ODBC driver does.
