The reason to *keep* them is compatibility. The reason they are like that to start with is because that is the naming pattern used in the system catalogs: 3 letters indicating the catalog, plus additional letters or words. It is useful to use the same name in views such as pg_stat_replication, so you can easily join different views and catalogs. -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
