Well, configure didn't find PQunescapeBytea() when checking out libpq.

It's doubtless NOT a problem of running PostgreSQL 7.2, and I think
I've changed Configure in later releases to NOT give that diagnosis.
It's probably that it couldn't find libpq to link against, or some
such thing.

There's probably some further clue as to why in config.log, which is
generated by the configure script.  Look near the bottom for an error
message.  Alas, configure is verbose enough that the relevant error is
probably 100 lines before the end of the log file :-(.
