terse advice:

write it down (at least for rewrite rules).

less-terse advice:

for instance-level rules, you can say
	retrieve (pg_prs2rule.all)
and a bunch of stuff (halfway-explained in the back of the ref 
manual) comes out.  part of this stuff is the text of the rule.

for rewrite rules, the human-readable text of the rule is never 
stored anywhere, so unless you can read the internal query plan 
format, you're pretty much out of luck.  you can get the query
plans by 
	retrieve (pg_rewrite.all)
