bizgres - bizgres: Add new psuedo threshold type 'IGNORE' - queries

Log Message:
-----------
Add new psuedo threshold type 'IGNORE' - queries whose cost is less than this
are not queued at all! This should make queueing work better with ad-hoc
tools that do a lot of catalog lookups before running actual queries.

Initdb is forced (changes to pg_resqueue).
