Hello Members,

 

We have the below PostgreSQL database recently migrated from Oracle.

 

The postgres DB parameters are attached here.

 

# DB Version: 10

# OS Type: Linux

# Total Memory (RAM): 30 GB

#CPU

nproc --all

There is huge slowness in the database now with any queries.

 

Oracle - Select * from TABLENAME- in takes  0.009 milliseconds

PostgreSQL - Same query takes more than 2 minutes.

Have you validated that the Postgres server has the same indexes?

If so, did you ANALYZE all the tables?
