Of course, with the server and client on the same machine, the server
and the client dynamic libs are very likely to follow the same
'non-standard' as the libpq.so is likely to be from the same build or
package as the server is.

These are real risks, of course.  I have personal experience with the
statically linked client and differing so version number cases.

And, yes, to echo your previous sentiment, if it breaks, the
distributor/packager is not the one that gets the compliants -- the
PostgreSQL community does.

So, for future discussion, a compromise will have to be arranged -- but
this really isn't a 7.1 issue, as this isn't a 'bugfix' per se -- you
have fixed the immediate problem.  But this is something to consider for
7.2 or later, as priorities are shuffled.
