Too late ;-). I just finished ripping out the unneeded parts and
applying.
I made a few minor changes too, mostly removing unnecessary code
(you don't need to call nameout, everyone else just uses NameStr)
and trying to line up stylistically with other code. One actual
bug noted: you were doing this in a couple of places:
+ tuple = SearchSysCache(RELOID, ObjectIdGetDatum(reloid), 0, 0, 0);
+ if (!HeapTupleIsValid(tuple)) {
+ elog(ERROR, "has_table_privilege: invalid relation oid %d", (int) reloid);
+ }
+
+ relname = NameStr(((Form_pg_class) GETSTRUCT(tuple))->relname);
+
+ ReleaseSysCache(tuple);
Since relname is just a pointer into the tuple, expecting it to still
be valid after you release the syscache entry is not kosher. There are
several ways to deal with this, but what I actually did was to make use
of lsyscache.c's get_rel_name, which pstrdup()s its result to avoid this
trap.
