Firstoff, 'select' is nor a unix command, neither
a postgresql program.
So you need something like:
su postgres -c "psql -c 'select count(*) from TABLE where xxxxxx'"
If you are the only one with an account on the machine
then you might try to tweak ~postgres/data/pg_hba.conf
and set method 'trust' for local access (no tcpip,psql without the -h
option) .
Also you could set env variables PGPASSWORD, PGUSER.
