Another dirty hack:
MAGIC=\! psql -Xc "select datname from pg_database WHERE datname $MAGIC~ 'template|postgres' ORDER BY datname;"
MAGIC=\! psql -Xc "select datname from pg_database WHERE datname $MAGIC~ 'template|postgres' ORDER BY datname;"

This statement runs great from the psql prompt. Does exactly what I want.select datname from pg_database WHERE datname !~ 'template|postgres' ORDER BY datname;But it doesn't work so well from the bash prompt. Not escaping the "!" generates a bunch of garbage, while escaping throws an sql syntax error.psql -Xc "select datname from pg_database WHERE datname \!~ 'template|postgres' ORDER BY datname;"
