    Add CheckTableNotInUse calls in DROP TABLE and DROP INDEX. · eff027c4
    Tom Lane authored
    Recent releases had a check on rel->rd_refcnt in heap_drop_with_catalog,
    but failed to cover the possibility of pending trigger events at DROP time.
    (Before 8.4 we didn't even check the refcnt.)  When the trigger events were
    eventually fired, you'd get "could not open relation with OID nnn" errors,
    as in recent report from strk.  Better to throw a suitable error when the
    DROP is attempted.
    
    Also add a similar check in DROP INDEX.
    
    Back-patch to all supported branches.
