Hi,I have 2 PG servers with same h/w and configuration and they are not in replication.On server A it takes 20 minutes to execute the script.On server B it takes more than 20 hours. (Seems to be stuck with create index and and create foreign key steps)Any guidance to troubleshoot this would be highly appreciated.Thanks & Regards,Sumeet Shukla
Check for long running queries on the server that is taking longer. If it's things like CREATE INDEX or ALTER TABLE statements that are being blocked, a transaction running on the table involved will cause those commands to be held until those transactions complete.
If it's normal read/write queries to that are taking longer, ensure the database statistics are up to date by running an analyze.В списке pgsql-performance по дате отправления:
