The line:
role_settings = DatumGetArrayTypeP(datum);
should be DatumGetArrayTypePCopy(), because it's being pfree()d later.
The existing code will sometimes make a copy and sometimes not, e.g.:
-- settings are contrived to make the datum inline
CREATE USER u1;
ALTER ROLE u1 SET search_path = 'public, pg_catalog, pg_temp';
ALTER ROLE u1 SET work_mem='64MB';
ALTER ROLE u1 SET statement_timeout='30s';
ALTER ROLE u1 SET lock_timeout='10s';
ALTER ROLE u1 SET idle_in_transaction_session_timeout = '60s';
SELECT pg_get_role_ddl('u1');
ERROR: pfree called with invalid pointer 0x7986dd0c7cc8 (header
0x0000400600000000)
Yes, it appears to be a bug. Attached a patch to fix this. Tested with
the
attached patch and don't see server crashing after that.
Thanks, pushed.
cheers
