Replicate generated columns when specified in the column list.
This commit allows logical replication to publish and replicate generated
columns when explicitly listed in the column list. We also ensured that
the generated columns were copied during the initial tablesync when they
were published.
We will allow to replicate generated columns even when they are not
specified in the column list (via a new publication option) in a separate
commit.
The motivation of this work is to allow replication for cases where the
client doesn't have generated columns. For example, the case where one is
trying to replicate data from Postgres to the non-Postgres database.
