Обсуждение: how to view original source of rules?

I know about this query...

  SELECT * FROM pg_rewrite where r.rulename = 'myrule';

...but the output is none too friendly to look at.

Anyone know how one can see something closer to the original input
source of a rule via psql?

Did you look at the pg_rules view?  Also look at its definition (\d
pg_rules), it uses a function for converting the parsetree of the rule
into a human readable version, pg_get_ruledef(text).  You can probably
use the same function for your own purposes.
