Hi
Could anyone please help me in understanding the internals of PostgreSQL?
Whenever I execute queries on two different tables (same database) from two
different clients simultaneously, it takes longer to execute that query for
one of the client (execution time is less if I do not execute these queries
simultaneously). I am confused why should the queries on completely
different tables interfere with each other?
Thank you in advance!
Regards,
Preetika
