Bug reference:      17518
Logged by:          Bob Krier
Email address:      rkrier@cleo.com
PostgreSQL version: 12.10
Operating system:   AWS RDS
Description:       

We are getting an error executing a delete statement from JDBC like
follows:

DELETE FROM "EBI"."LOG_OF_CONNECTION" WHERE "DATE" < {some java date in
milliseconds}.  The error is as follows:
--->   "SQLException: ERROR: new multixact has more than one updating
member"

If you try this via psql you don't see the error though?

Do you get the same error if you delete a single row using a PK instead of a bunch of rows via a date inequality?

Does it seem to matter which rows are being deleted in general, or how many?  How about columns?

Can you construct a self-contained minimal reproducer?

Does it manifest on standalone community PostgreSQL or just RDS?
