Throw away most of the existing logic for this, as it was very inefficient thanks to expensive sub-selects executed to collect ACL data that we very possibly would have no interest in dumping. Reduce the ACL handling in the initial per-object-type queries to be just collection of the catalog ACL fields, as it was originally. Fetch pg_init_privs data separately in a single scan of that catalog, and do the merging calculations on the client side. Remove the separate code path used for pre-9.6 source servers; there is no good reason to treat them differently from newer servers that happen to have empty pg_init_privs. Discussion: https://postgr.es/m/2273648.1634764485@sss.pgh.pa.us Discussion: https://postgr.es/m/7d7eb6128f40401d81b3b7a898b6b4de@W2012-02.nidsa.loc
