yum packages for 9.5 vs <=9.4

the yum packages for 9.5 apparently changed the path of the socket from
/tmp to /var/run/postgresql

I have several versions installed on the same dev system running on
different ports.... for 9.1 through 9.4 this was no problem, but since
I installed 9.5, I now have to specify -h /tmp -p XXXX to connect to an
earlier version, this has raised havoc with my scripts and stuff, for
instance this script invoked from crontab no longer works on the earlier
versions...

#!/bin/bash
## postgres backup script
DD=$(date +%a)
PP=/backups/pgsql/svfis-kvm3
for p in 5432 5433 5434 5435; do
pg_dumpall -p $p -g -f $PP/pg_dumpall.$p.globals-$DD.sql
for db in $(psql -p $p -tc "select datname from pg_database where
not datistemplate"); do
pg_dump -Fc -p $p --schema-only -f $PP/pgdump.$p.$db.$DD.dump -d $db
done
done
