PostgreSQL caches some of the data from the database. If you, for
example, wanted to have most of your database remain in memory, for speed,
then you would want to have more memory than the minimum needed to
handle the queries.

I meant that you would want to be sure that PostgreSQL is configured
with regard to the expected load and the number and mem requirements of
queries. You might see out of memory errors under load.
