pgsql: Make vacuum_defer_cleanup_age be PGC_SIGHUP level, since it's not - Mailing list pgsql-committers

Log Message:
-----------
Make vacuum_defer_cleanup_age be PGC_SIGHUP level, since it's not sensible
to have different values in different processes of the primary server.
Also put it into the "Streaming Replication" GUC category; it doesn't belong
in "Standby Servers" because you use it on the master not the standby.
In passing also correct guc.c's idea of wal_keep_segments' category.
