I've got a list of old resource requirements.
I want to know how far off they are and if anything
crucial is missing. My usual recommendation is
"as much as you can afford" so I don't usually deal
with real numbers :)
RAM:
Number of connections * 2MB
Disk:
Program and Manual 8-15MB
Regression Tests 30MB
Compiled Source 60-160MB
Storage for user data ( as much as you can afford :)
Please copy me since I'm not officially on this list.
Thanks,
Elein

These look very approximate.

That's not a bad recommendation, but not an actual requirement. It really
depends on how much sort_mem you need. Could vary from 0.5mb to as much
as 256mb per connection, depending on your application.

Well, my compiled source takes up 87mb, and the installed PostgreSQL seems
to be about 41mb including WAL. Not sure how much the regression tests
are.
