Implement pipeline mode in libpq
Pipeline mode in libpq lets an application avoid the Sync messages in
the FE/BE protocol that are implicit in the old libpq API after each
query.  The application can then insert Sync at its leisure with a new
libpq function PQpipelineSync.  This can lead to substantial reductions
in query latency.

Robert Haas ac44595585 Move PG_USED_FOR_ASSERTS_ONLY before initializer.
Erik Rijkers reported a compile failure, and I think this is probably
the reason.

Robert Haas 9706092839 Add pg_amcheck, a CLI for contrib/amcheck.
This makes it a lot easier to run the corruption checks that are
implemented by contrib/amcheck against lots of relations and get
the result in an easily understandable format. It has a wide variety
of options for choosing which relations to check and which checks
to perform, and it can run checks in parallel if you want.
