Database fixed size
Hey,
Is there anyway to limit a database size?
For example, I need to create a database for user X and I don't want it to
use more than 5 GB.

You can create a tablespace on a device with limited size.
Then you can create the database on that tablespace.

Note the reference to tablespace. It's unwise to just put the whole
cluster on a tiny device (or equivalently, attempt to solve this with
OS-level disk quotas applied to the whole installation). The reason is
that PG gets very unhappy if it runs out of WAL space. Hitting a limit
on table size per se behaves a bit more sanely, though even there you
can get into trouble --- for instance, in some situations VACUUM will
try to allocate additional disk space, making recovery harder.

So how did heroku limit the database size per user?
I thought about creating triggers on insert and updates but that will lead
to bad performance
