Subject: [PATCH v14 06/19] error safe for casting inet to other types per
pg_cast
select castsource::regtype, casttarget::regtype, castfunc,
castcontext,castmethod, pp.prosrc, pp.proname from pg_cast pc join pg_proc pp on
pp.oid = pc.castfunc and pc.castfunc > 0
and castsource::regtype = 'inet'::regtype
order by castsource::regtype;
castsource | casttarget | castfunc | castcontext | castmethod | prosrc | proname
------------+-------------------+----------+-------------+------------+--------------+---------
inet | cidr | 1715 | a | f | inet_to_cidr | cidr
inet | text | 730 | a | f | network_show | text
inet | character varying | 730 | a | f | network_show | text
inet | character | 730 | a | f | network_show | text
(4 rows)
inet_to_cidr is already error safe.
