I thought removal of a table from inheritance hierarchy would delete it
from publications that its parents are part of.
One more option is for OpenTableList() called by CreatePublication() and
AlterPublicationTables() to not disregard inheritance, as if ONLY was
specified.
Related: I noticed that if you dump a database containing a publication
and an inheritance parent is published by it, loading that into another
database causes the following error for each child.
ERROR: relation "bar" is already member of publication "foo_pub"
Because when foo, the parent, is added to foo_pub publication, bar (a
child of foo) is added implicitly.
Thanks,
