Run a test instance from the source directory

Hi,

I'd like to edit, compile, run, profile and debug in a loop. To do
that I put pg_sleep(3600) in the regression test suite.

That way I can easily change a file, 'make check', and then run some
SQL from another terminal.

Is there a 'better' way to run postgres after building? In a way that
doesn't break 'make check'?

Thanks,

Groeten, Arjen
