The sole reason we jumped from Postgres 1.09 to 6.0 was that in Postgres 1.0.X, $PGDATA/PG_VERSION contained '5', meaning when Berkeley went from University Postgres 4.2 to Postgres95 1.0, they didn't reset PG_VERSION. We really had no way of going to Postgres 2.0 unless we were prepared to have data/PG_VERSION never match the major version number. -- Bruce Momjian <br...@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + As you are, so once was I.
