Обсуждение: no entry on pg_database for a live database
I have a situation I thought was impossible.
I have a live postgres database with 4 application tables. I can access it through PSQL.
But there is no record of this database on the PG_DATABASE catalog table.
And I therefore cannot perform a PG_DUMP backup because it errors with,
You guessed it, ‘No entry on pg_database’ We haven’t done backups
As these are workfile temporary tables. But I’ve primed one of these
Tables with permanent data for performance.
I’m running version 7.4.5. Do I have to do a drop-recreate or is there
Some other way around this?
Any ideas would be appreciated

Try vacuuming pg_database.
If that works, it means your routine vacuuming procedures need some
re-thinking, because they are missing (at least) pg_database.

You're doing yourself no favors by failing to update. The current
release in that branch is 7.4.19.

My first suggestion would be to try it with 7.4.19 (using a copy of your data files of course) As well as planning an upgrade to 8.1 or 8.2 -- Shane Ambler pgSQL (at) Sheeky (dot) Biz Get Sheeky @ http://Sheeky.Biz
Thanks Tom - that did the trick
We will be upgrading to 8.2 within the next couple weeks.

In that case, you were missing pg_database and probably other system
catalogs too in your vacuuming.

I'd recommend making sure you have vacuumed all system catalogs before
you try to pg_dump, else some of the catalog entries may be invisible
to pg_dump :-(
FWIW, 8.2 should be proof against this type of problem recurring,
because it takes proactive steps to avoid transaction ID wraparound.
7.4 left that up to the DBA ...
