Just so everybody knows, we're starting the migration for good of openacs.org to PG 7.2.3.
To avoid some of the problems we had with the 3.2.5 -> 4.6 migration, we are going to bring the site down, with a temporary "In Maintenance" page in its place.
That way we can make a pg_dump/reload of the database and avoid problems of lost posts/users/etc.
Hang on tight.
