Hi,

I'm trying to run 'make check' on a 64bit Debian unstable. That aborts
after 60 seconds due to not being able to connect to the postmaster.

I figured that there's nothing wrong with the postmaster, rather psql
can't start up, because it gets linked against an older libpq.so.5. It
looks like for some reason, it doesn't respect the LD_LIBRARY_PATH env
variable, see ldd output:

markus@argodan:/home/markus/projects/pgsql/sources/current/pgsql/src/test/regress#

Giving it an additional LD_PRELOAD for the newish libpq.5.1 helps:

Somebody have an idea on what's wrong here? Thanks.

Smells suspiciously like an rpath problem to me. What are your configure
settings?

cheers

Ah, yeah, I see. Using something else than --prefix=/usr helped.

Thanks for the hint!
