The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/16/logical-replication-col-lists.html
Description:
The documentation on this page mentions:
"If no column list is specified, any columns added later are automatically
replicated."
It feels ambiguous what this could mean. Does it mean:
1/ That if you alter the table on the publisher and add a new column, it
will be replicated
2/ If you add a column list later and add a column to it, it will be
replicated
In both cases, does the subscriber automatically create this column if it
wasn't there before? I recall reading that the initial data synchronization
requires the schema of the publisher database to be created on the
subscriber first. But then later updates sync newly created columns? I don't
recall any pages on logical replication mentioning this, up to this point.
