If we had to supply gcj along with PostgreSQL in order for PostgreSQL to
work, I guess that would mean gcj was incorporated in PostgreSQL - that
would mean PostgreSQL would become subject to GPL protection.

If CREATE FUNCTION called a java compiler (which might or might not be
gcj) that PostgreSQL did not supply, that compiler would not be
incorporated. If there were no java compiler, java functions would not
work, but otherwise PostgreSQL would be unaffected. It would be the
same as any of the tools that get called in our shell scripts, many of
which may be GNU utilities, including, of course, the shell itself.

As for the virtual machine, I think that is what libgcj supplies, and it
is specifically excluded from having GPL effects by its licence.
