SELECT * FROM ( SELECT s.t AS "Ordering", (string_to_array(pg_read_file( 'pg_hba.conf',
0, (pg_stat_file('pg_hba.conf')).size ), '\n'))[s.t] AS "Line" FROM generate_series(
1, array_upper( string_to_array(pg_read_file( 'pg_hba.conf',
0, (pg_stat_file('pg_hba.conf')).size ), '\n'), 1 ) ) AS
s(t)
) AS foo
WHERE "Line" !~ '^#'
AND "Line" !~ '^\s*$'
