Wait, how to find out how many connections there are, or how many can
a particular db handle.
For this kind of thing, look at the admin functions in the pgsql-sql docs:
http://www.postgresql.org/docs/8.3/interactive/functions-admin.html
specifically you want something like:
select datname from pg_stat_activity;
select datname, count(datname) from pg_stat_activity group by datname;

you may not be measuring properly. When you say it's using 70-80 MB
how do you know this? The numbers you see in top aren't necessarily
what some folks think they ar.
