Fill in extraUpdatedCols in logical replication
The extraUpdatedCols field of the target RTE records which generated
columns are affected by an update. This is used in a variety of
places, including per-column triggers and foreign data wrappers. When
an update was initiated by a logical replication subscription, this
field was not filled in, so such an update would not affect generated
columns in a way that is consistent with normal updates. To fix,
factor out some code from analyze.c to fill in extraUpdatedCols in the
logical replication worker as well.
