[turba] [patch] Fix sql driver's use of SQL "IN ()"

[Chuck Hagenbuch]

Quoting "Jason M. Felice" <jfelice at cronosys.com>:

> PostgreSQL throws a parse error when it sees an SQL IN expression with an
> empty value list.  It probably shouldn't, but we should save a trip to the
> database in any case.

Committed, thanks.
