[HACKERS] beta3 vacuum crash
I haven't tried everything to recover from this yet, but will quickly try to document the crash before I lose track of what exactly went into it and what I did: Basically I deleted a table and then ran vacuum verbose, with the net result that I cannot connect to this database anymore with the error: frank@kelis:/usr/local/httpd/htdocs > psql mpi psql: FATAL 1: Index 'pg_trigger_tgrelid_index' does not exist This is, fortunately, not the production system but my development machine. I was going to go live with this in a couple of week's time on beta3. Should I reconsider and move back to 7.03 (I'd hate to cuz I'll have rows bigger than 32K, potentially . . . )?

I have 3 machines with an identical setup, two of which I already had moved to beta3. On those, the error does not occur. On the December 13 version, I can reproduce the error, which obviously has been fixed. Sorry about the confusion. - Frank
