pgsql: Fill in extraUpdatedCols in logical replication

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.
