Bug reference:      17518

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");
