SELECT pg_database_size('DB1')  takes 60ms for 7948 kB size DB. Is there any
way to reduce the time taken or any other ways to find data base size?

Thanks and Regards,
S.Sangeetha

What is the version of PostgreSQL you are using ?

You can execute the command "\l+" which will list all the databases and
their sizes.

Or you can execute "\l+ <database-name>".

Depending on your needs, you could also take the sum of 
pg_class.relpages and multiply that by BLKSZ.
