Ignoring the warnings not to use a beta product on a production database I had been running 8.3beta1. When I saw that it had hit 8.3RC1 I decided to upgrade and folowing the usual data compatibility within major versions I did not do a pg_dump, in fact my last dump was when I loaded the beta on 10th October. I get the following error FATAL: database files are incompatible with server Unfortunately, I cannot find my copy of the beta1 source files and they are no longer available on the internet. All I had was a download of beta4, which I never used. I fired it up hoping that the data incompatibility was between beta and RC, but the error reads: FATAL: database files are incompatible with server DETAIL: The database cluster was initialized with CATALOG_VERSION_NO 200709301, but the server was compiled with CATALOG_VERSION_NO 200711281.
What can I do, a dump is impossible because I cannot re-install the version that the database was last used with (it should have been first initialised on 8.2, as I went to the beta to experiment with enum having recently returned from MySQL).
Any help appreciated, including links to a download of beta1 that still works.
