Re: PostgreSQL backend process high memory usage issue - Mailing list pgsql-general

No. The highmemory usage issueis stll there.

We could change select count(*) to select * or select 1 if you like. Therre
is no data in the tables anyway.

Not to beat on your test some more, but spamming count(*) is probably
not a good real world indicator of application performance (but it
