Oh, and if you *are* debugging a PostgreSQL process under the same uid
as your own, adjust the ptrace_scope i the yama security module. Like
the error message above tells you to.
Details here:
http://askubuntu.com/questions/41629/after-upgrade-gdb-wont-attach-to-process
which I found by *searching for the error message text*.
BTW, in general I recommend that when you're modifying and debugging
PostgreSQL you run it under your normal user account using 'postgres' or
'pg_ctl', rather than messing with an operating system installation.
It's much easier.
