I used pgcompacttable on Windows with PSQL versions 9.4 and 11 for a long time. Everything went smooth with version from 2020-09-01
Yesterday I tried updated version (2021-09-10) and got few broken databases on different servers.
ERROR: could not open relation with oid
I have log from only one server. At first glance it doesn't have anything interesting, no errors. On a second server log had few "SQL errors" which never occurred before.
Please revert latest changes.
Unfortunately I'm unable to help with further testing and most likely would just use previous version.
Thanks.
