Hi guys, I have a PostgreSQL 9.5 server, which started showing the following message in the log: ,ERROR,54000,"multixact ""members"" limit exceeded","This command would create a multixact with 2 members, but the remaining space is only enough for 0 members.","Run a database-wide VACUUM in database with OID 139059 with reduced vacuum_multixact_freeze_min_age and vacuum_multixact_freeze_table_age settings.",,,"SQL statement ""SELECT 1 FROM ONLY ""public"".""alf_server"" x WHERE ""id"" OPERATOR(pg_catalog.=) $1 FOR KEY SHARE OF x""","insert into I started the vacuum in the database , but the same for the size ,I believe it will take a long time. Is there any way to increase this limit member while the vacuum is running to free up the application? thanks a lot,
