With memoize enabled PG14 append tests produce a very different
plan compared to previous PG versions. To make comparing plans
between PG versions easier we disable memoize for PG14.
PG14 also modified how EXTRACT is shown in EXPLAIN output
so any query using EXTRACT will have different EXPLAIN output
between PG14 and previous versions.
We explicilty filter paths for compressed chunks that
have spurious join clauses between the compressed chunk and
the original chunk or hypertable. However there are other
cases where a chunk could be a child rel
(i.e. RELOPT_OTHER_MEMBER_REL) such as when the chunk is
referenced as part of a UNION ALL query. We remove all
paths that have spurious join clauses between the compressed
chunk and any implied parent for the chunk.
Fixes#2917
This PR reduces the dataset size in the transparent_decompression
test to make it finish in a more reasonable time. It also splits
the test and modifies queries that used now(). Due to the change
in dataset size the resulting diff is rather large but is mostly
row count changes in the plan but the actual plan shapes don't
change. In addition to those changes to some LATERAL queries
additional constraints have been added to reduce the number of
loops.
