pgsql: In the stats test, delay for the stats collector to catch up
Log Message:
-----------
In the stats test, delay for the stats collector to catch up using a
function that actually sleeps, instead of busy-waiting. Perhaps this
will resolve some of the intermittent stats failures we keep seeing.

Good. I was seeing these random stat failures too.

Any chance of exposing a sleep function to the user? It's admittedly
of limited utility and it can usually be done on the client side,
but I've occasionally wanted one for testing with simple SQL scripts.
In such cases I end up writing a one-liner with PL/Perl, PL/Tcl, etc.

Agreed --- I was thinking the same thing.
