Which version did you say you were using? There is no assignment of
LDFLAGS_SL in either libpq's or libpgtcl's Makefile in 6.4 --- that's
being done in src/Makefile.shlib now. I wonder whether you have some
6.4 beta version.
Still, this -Bdynamic switch looks interesting. Constantin, if you
add that to LDFLAGS_SL in src/Makefile.shlib (in the Linux case, of
course) does it work any better for you?

That looks pretty good...

6.4 libpq (and hence libpgtcl) cannot talk to a 6.3.2 backend at all.
But that should have resulted in a failure in the pg_connect statement,
because it would have been detected by the old backend as an unsupported
protocol version number.
I wonder whether what you actually have is a couple of different pre-6.4
code snapshots. We changed the FE/BE protocol a couple of times between
6.3.2 and 6.4beta1, but we only changed the protocol version number
once. Some of those intermediate states of the code would have failed
to talk to each other with peculiar symptoms, perhaps like this.
BTW, which Linux distribution are you using?
