PostGree is a system I am not familiar with; this list is for
discussion of PostgreSQL, sometimes aliased as "Postgres," so I will
assume you are referring instead to PostgreSQL.

PostgreSQL does have limitations; each connection spawns a process,
and makes use of its own "work_mem", which has the result that the
more connections you configure a particular backend to support, the
more memory that will consume, and eventually your system will
presumably run out of memory.

The size of the database doesn't have as much to do with how many
users you can support as does the configuration that you set up.
