Hi Stephen, thanks for responding. Yes I do have spatial indexes as prior
processing was filtering using ogr2ogr to select desired rows in the table
for subsequent processing. It is my understanding that ogr2ogr defaults to
producing these spatial indexes unless specifically instructed not to.

Best regards, Chris
