Thread: pgsql: Add an Accept parameter to "simple" dictionaries.

Log Message:
-----------
Add an Accept parameter to "simple" dictionaries.  The default of true
gives the old behavior; selecting false allows the dictionary to be used
as a filter ahead of other dictionaries, because it will pass on rather
than accept words that aren't in its stopword list.
