We have database servers where the PostgreSQL instances are configured
to support on the order of a thousand concurrent connections, and
definitely have hundreds active at a time fairly frequently, so that
kind of scalability is certainly possible.
To support that, we have rather powerful hardware; that's not running
on "a cheap PC with an IDE disk drive."
It would actually be pretty unusual for the sort of application you
are describing to actually require thousands of concurrent
connections. There may be thousands of users accessing the
application, but the database access is likely to be sporadic.
Web application frameworks typically offer support for "connection
pools" so that a much smaller number of actual database connections is
used to support a large number of users.
As for quantity of data, any respectable database can store very large
quantities of data. "Many gigabytes" should be easy. Terabytes are
where the challenges begin, but there certainly are organizations
using PostgreSQL to support terabyte-sized databases.
