Re: could not access status of transaction pg_multixact issue

Adrian, the query for the 0000 removal returns f.

Alvaro, Yes the pg_upgrade was done with 9.3.4. Following the bug #11264
you referenced:

select datname, datfrozenxid, datminmxid from pg_database;

datname | datfrozenxid | datminmxid
--------------+--------------+------------
acustream | 1799 | 1

It's not clear which lines from pg_controldata to use for updating
pg_database.datminmxid.

I also assume I would do the pg_database update on a idle database.
