I am developing an application which needs to:

1.)  connect to a database under the control of the postmaster running
on the same machine,
2.)  disconnect from that database,
3.)  connect to a database under the control of a postmaster running on
a different machine.

The way I attempted to accomplish this behavior was to use putenv() to
change the PGHOST and PGPORT environment variables.  

The problem is that  Postgres appears to ignore the environment
variables once PQhost and PQport are set and neither PQfinish() nor
PQsetdb() (which calls PQreset()) seem to clear these variables.

Any suggestions?

Robert
