--- this file is only executed at startup if the function hafbe_indexes.do_haf_indexes_exist()
--- returns true.  This function has a list of the indexes created in this file, and returns
--- true if they all exist.  If you add, remove, or rename an index created in this file, you
--- must make a corresponding change in that function
---
--- We do this because the ANALYZE at the end of this file is slow, and only needs to be run
--- if we actually created any indexes.  
-
-
--- Note, for each index below, we first check and see if it exists but is invalid; if so, we drop it.
--- That will cause it to be recreated by the subsequent CREATE IF NOT EXISTS
--- We could chec/drop all of the indexes in a single DO block at the top of the file, which might
--- look cleaner.  But I figure this way, someone doing cut & paste is more likely to grab both the
--- drop and the create.
