Hi,

Some patches of this thread have fallen though the cracks for more
than 2 months now, so I am re-posting them so that do not get
overlooked any longer.

For v49 [1] there were 2 patches:
v49-0001-Enable-support-for-publish_generated_columns-par
v49-0002-DOCS-Generated-Column-Replication

Then, at v50 [2] there were 2 patches:
v50-0001-Replicate-generated-columns-when-publish_generat
v50-0002-Tap-tests-for-generated-columns

Notice the DOCS patch is missing in v50.

Those v50* patches were then pushed to master. But, that was 2 months ago.

~~

So, the v49-0002-DOCS patch (which added a new section to Chapter 29)
remains still unpushed.

Meanwhile, it was reported [3] that pubgencols attribute of the
pg_publication catalog is missing from the docs.

~~

In this post, I have attached v51* patches where:

v51-0001 - This is a rebase of the missing DOCS patch from v49.

v51-0002 - This is the pg_publication catalog missing pubgencols
attribute patch.

~~~

Future -- there probably need to be further clarifications/emphasis to
describe how the generated column replication feature only works for
STORED generated columns (not VIRTUAL ones), but IMO it is better to
address that separately *after* dealing with these missing
documentation patches.
