When I try to run psql on 64 bit sid I get this error message:

/usr/lib/postgresql/9.4/bin/psql: symbol lookup error: /usr/lib/postgresql/9.4/bin/psql: undefined symbol: PQconninfo

I needed to run some 32 bit programs so I had to install the 32bit version. But I wonder if it added some dependencies that is causing the current problem. If its an architectural conflict then I'd like to install a 64bit psql as well, but I still need them both. Reinstalling postgresql-client doesn't change things so it seems that a 64bit is not being installed unless psql is 32bit only.

Running ` ldd /usr/lib/postgresql/9.4/bin/psql' produces:

I am running Debian Sid, but I don't think that is the problem.

    It's not an architecture issue. It looks like your psql is getting linked to an old version of libpq.so.5. dpkg -S /lib/i386-linux-gnu/libpq.so.5? – Craig Ringer Nov 6 '15 at 1:11
  • It seems that for some reason apt-get install postgresql-client was installing postgresql-client:i386 probably because it I needed it for some 32 bit programs. I had to use apt-get install postgresql-client-9.4 to get the 64bit version to install – vfclists Nov 8 '15 at 1:09
