You can get more information on that with the attached patch, which
might be a useful addition in general.  The problem comes from this:

exec sql connect to unix:postgresql://localhost/connectdb?connect_timeout=14 user connectuser;

and the updated error message is:

ECPGconnect: could not open database: FATAL:  invalid command-line arguments for server process: connect_timeout=14

Because connect_timeout is a separate libpq connection parameter, but
now it's stuck into "options".  It might have worked more or less by
accident before.

It's not clear to me why this only appears on checktcp.  And why we
don't run those tests by default.  That should be clarified, because
there are also other failures in that test that show that it hasn't been
run in a while.
