I think the consensus in this thread (and the previous ancient ones) is
that it's not worth it. It's one thing to introduce new commands with the
pg_ prefix, and it's a completely different thing to rename existing ones.
That has inherent costs, and as Tom pointed out the burden would fall on
people using PostgreSQL (and that's rather undesirable).

I personally don't see why having commands without pg_ prefix would be
an issue. Especially when placed in a separate directory, which eliminates
the possibility of conflict with other commands.
