Обсуждение: BUG #15807: pg_upgrade does not account for renaming of system catalog column names

The following bug has been logged on the website:

Bug reference:      15807
Logged by:          Richard Yen
Email address:      richyen3@gmail.com
PostgreSQL version: 10.8
Operating system:   CentOS 6
Description:

example: pg_stat_replication.sent_location was renamed to
pg_stat_replication.sent_lsn in v10.  If a view in 9.6 refers to
pg_stat_replication.sent_location, pg_upgrade fails entirely because "column
pg_stat_replication.sent_location does not exist"

Yeah, that's a documented compatibility issue, per the v10 notes:

  * Rename WAL-related functions and views to use lsn instead of location

It is not pg_upgrade's job to fix such things.  Sorry.
