This change adds equivalence class members for non segment by attributes of compressed tables. Before the change introduced by this PR, we added equivalence members to the compressed chunk only for segment by columns. If we have a join condition like: hyper.segment_col = A.col1 and hyper.compressed_attr = A.col2 The compressed rel had EM only for compressed_chunk.segment_col = A.col1 When a parameterized path is created for the compressed chunk, it has only 1 clause (corresponding to the segment by EM ) in its list of ppi_clauses. The other clause is missing since it did not have an EM. A parameterized path is expected to carry all the clauses that come from the outer_rel for the join (table A in this case).Since the ppi_clauses did not have all the clauses that come from table A, we ended up missing a join condition (for table A) when we had a parameterized index path for the compressed chunk. Fixes timescale#2673

In particular the fixes contained in this maintenance release address issues in continuous aggregates, compression, JOINs with hypertables, and when upgrading from previous versions. **Bugfixes** * #2502 Replace check function when updating * #2558 Repair dimension slice table on update * #2619 Fix segfault in decompress_chunk for chunks with dropped columns * #2664 Fix support for complex aggregate expression * #2800 Lock dimension slices when creating new chunk * #2860 Fix projection in ChunkAppend nodes * #2865 Apply volatile function quals at decompresschunk * #2851 Fix nested loop joins that involve compressed chunks * #2868 Fix corruption in gapfill plan * #2883 Fix join qual propagation for nested joins * #2885 Fix compressed chunk check when disabling compression * #2920 Fix repair in update scripts **Thanks** * @akamensky for reporting several issues including segfaults after version update * @alex88 for reporting an issue with joined hypertables * @dhodyn for reporting an issue when joining compressed chunks * @diego-hermida for reporting an issue with disabling compression * @Netskeh for reporting bug on time_bucket problem in continuous aggregates * @WarriorOfWire for reporting the bug with gapfill queries not being able to find pathkey item to sort * @zeeshanshabbir93 for reporting an issue with joins

This change adds equivalence class members for non segment
by attributes of compressed tables. Before the change
introduced by this PR, we added equivalence members to the
compressed chunk only for segment by columns. If we
have a join condition like:
hyper.segment_col = A.col1 and hyper.compressed_attr = A.col2
The compressed rel had EM only for
compressed_chunk.segment_col = A.col1
When a parameterized path is created for the compressed chunk,
it has only 1 clause (corresponding to the segment by EM )
in its list of ppi_clauses. The other clause is missing since
it did not have an EM. A parameterized path is expected to carry
all the clauses that come from the outer_rel for the join
(table A in this case).Since the ppi_clauses did not have all
the clauses that come from table A, we ended up missing a join
condition (from table A) when we had a parameterized index path
for the compressed chunk.
Fixes #2673
