Well, I just re-tested it here, and it works fine for me (using 8.1.4,
but I don't see anything in the CVS logs indicating changes in the
relevant code since 8.1.2).  So I still think there's some sort of
pilot error involved here, but I'm running out of ideas about what.
You might want to try the strace experiment I suggested to confirm
that the postmaster is reading the file you think it is.

Could it be that the JDBC client creates a connection and keeps that connection open (common with connection poolilng)?  If you SIGHUP the postmaster, will it disconnect already connected clients or does it only reject new connections?

I say this since you said doing a restart fixes the problem.
