Comment 4 for bug 525016

ok, i cleaned it up and made a new install.
apt-get refuses to install libpq.so.

alex@srv:~$ /usr/lib/postgresql/8.4/bin/pg_ctl start -D /var/lib/postgresql/8.4/main -l /var/log/postgresql/postgresql-8.4-main.log -s -o -c config_file="/etc/postgresql/8.4/main/postgresql.conf"
/usr/lib/postgresql/8.4/bin/pg_ctl: error while loading shared libraries: libpq.so.5: cannot open shared object file: No such file or directory

alex@srv:~$ sudo find / -name libpq*
/usr/share/doc/libpq5
/usr/include/libpq

Does anyone have this issue with a new postgresql 8.4 install?
Who should install libpq5?
