How big a database will PostgreSQL support?

Hello,

We have a database project that we are going to be designing, and I
was wondering how big can things get? I am new at this stuff, so I
really have no idea as to what the limitations really are.
Does anyone have approximate numbers in terms of # of tables, rows and
columns? Are there any formulas or rules of thumb that one can apply?

Also, in terms of database design, am I better off having one big table
with 10 million rows or 1000 tables with 10000 rows?

Thank you for your assistance.
