Logged by:          Radim Kolar
Email address:      kolar.radim@gmail.com
PostgreSQL version: 8.3beta2
Operating system:   FreeBSD
Description:        libpq needs .so version raised to 6
Details:

/libexec/ld-elf.so.1: /usr/local/pgsql8.3/bin/psql: Undefined symbol
"PQconnectionUsedPassword"

both libpq from pgsql 8.2 and 8.3 are using same version
of .so 5. But libpq from 8.3 have new function PQconnectionUsedPassword. .so
version of 8.3 libpq needs to be raised to 6

/usr/local/pgsql8.3/lib/libpq.so.5

This is not a bug.  Major version bumps in sonames are for incompatible
changes, not for additions of new entry points.
