Logically, unlimited. Practically, because tables are stored as files,
at some point you might run out of inodes on your disk. You're more
likely to run out of disk-space first though, unless your tables are
small.
More directly, as the number of tables grow, so does the size of the
system catalogs. So this will show up as increased planning time.
Databases are just a way of dividing up tables. No strict limit, but
the number-of-files thing applies.
Actually, it's tables-per-database that's the relevent to planning
time, as the backend doesn't need to worry about tables in other
databases.
Hope this helps,
