Thanks. I've been looking more at this and I've made a few more
adjustments in the attached.
This delta patch should be applied against the
faster_partition_prune_v21_delta_drowley_v1.patch one I sent
yesterday. This changes a few comments, also now correctly passes the
context to get_partitions_excluded_by_ne_clauses and fixes a small
error where the patch was failing to record a notnull for the
partition key when it saw a strict <> clause. It was only doing this
for the opposite case, but both seem to be perfectly applicable. I
also made a small adjustment to the regression tests to ensure this is
covered.
I'm now going to start work on basing the partition pruning patch on
top of this.
