Обсуждение: pgsql: Migrate PGPROC's backendLock into PGPROC itself, using a new tra

Migrate PGPROC's backendLock into PGPROC itself, using a new tranche.

Previously, each PGPROC's backendLock was part of the main tranche,
and the PGPROC just contained a pointer.  Now, the actual LWLock is
part of the PGPROC.

As with previous, similar patches, this makes it significantly easier
to identify these lwlocks in LWLOCK_STATS or Trace_lwlocks output
and improves modularity.
