Not sure of why this is, but I just noticed that maps-test2001 has a newer Postgres version than maps2001:
-- maps-test2001 -- psql (9.4.8) SELECT version(); -- PostgreSQL 9.4.8 on x86_64-unknown-linux-gnu, compiled by gcc (Debian 4.9.2-10) 4.9.2, 64-bit -- maps2001 -- psql (9.4.6) SELECT version(); -- PostgreSQL 9.4.6 on x86_64-unknown-linux-gnu, compiled by gcc (Debian 4.9.2-10) 4.9.2, 64-bit
