The RAM/users question depends largely on what the database is used
for and what each user is doing in the database.
From what I understand, PostgreSQL is designed with stability and
reliability as key tenants. MySQL favors performance and ease of use. An
example is that, last I checked, MySQL doesn't have an equivalent to
PostgreSQL's 'fsync' which helps insure that data is actually written to
the disk. This costs performance but increases reliability and crash
recovery.
