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.
