BUG #17518: Getting Error "new multixact has more than one updating member" when trying to delete records.

The following bug has been logged on the website:

Bug reference:      17518
Logged by:          Bob Krier

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"

I've searched the web for this particular error and was only able to find
the source file
"https://github.com/postgres/postgres/blob/master/src/backend/access/transam/multixact.c",
but I don't know the conditions that cause it.  Is there any remedy to
this?


We have a table defined as follows:
CREATE TABLE "LOG_OF_CONNECTION" (
	"ID" bpchar(32) NOT NULL,
	"TYPE" int4 NOT NULL,
	"STATUS" int4 NULL,
	"DATE" int8 NULL,
	"MARKED_FOR_PURGE" int2 NULL,
	"CONNECTION_DIRECTION" varchar(1) NULL,
	"TARGET_DBP" bpchar(32) NULL,
	"ENDPOINT_ID" bpchar(32) NULL,
	"METHOD_MESSAGES" bytea NULL,
	"PERSISTENT_STORAGE_REQUESTED" int4 NULL,
	"PROCESS_USER_REF" int8 NULL,
	"CONNECTION_NUMBER" int4 NULL,
	"NOTIFICATION_TYPE" varchar(256) NULL,
	"TIME_SENT" int8 NULL,
	"CALC_RETURN_TIME" int8 NULL,
	"TIME_RECEIVED" int8 NULL,
	"IS_PROCESSED" int4 NOT NULL DEFAULT 0,
	"ENDPOINT_NAME" varchar(1024) NULL,
	"TRADING_PARTNER_ID" varchar(1024) NULL,
	"TRANSFER_ID" varchar(1024) NULL,
	"LOG_ORIGIN_OBJECT" varchar(1024) NULL,
	CONSTRAINT "LOG_OF_CONN_PK" PRIMARY KEY ("ID", "TYPE")
);
CREATE INDEX by_date_log_of_connection ON "EBI"."LOG_OF_CONNECTION" USING
btree ("DATE", "ID");
CREATE INDEX by_status_date_id3 ON "EBI"."LOG_OF_CONNECTION" USING btree
("ID", "TYPE", "STATUS", "DATE" DESC);
CREATE INDEX edi_late_ack_log_of_connection ON "EBI"."LOG_OF_CONNECTION"
USING btree ("ID");
