I need it for API and user interface testing. I want to be sure
things behave correctly when a long running query is interrupted.

In any case, I wonder how many people, not having a sleep() function,
effect a delay with a busy loop; an example of such has been posted
in response to the thread in pgsql-admin, and didn't the regression
tests do so until recently? That seems

What do people think of exposing pg_usleep() to the user? It's
sometimes useful to have a server-side sleep function, and people
do ask about it occasionally (e.g., Don Drake today in pgsql-admin).
It's easy enough to do in PL/Perl, PL/Tcl, etc., but since the
backend already has pg_usleep(), is

I'm not real enthused about it. Generally speaking, a sleep() on the
database side means you are idling while holding locks, and that does
not seem like something we want to encourage people to do.

Or in (trusted) plperl - see my post on admin.
I would have been a big fan of a sleep function once, for use in plpgsql,
but since I now have
