I will continue to experiment. The question is which option is better
(this would reduce the number of options):
pd_dump is the source server;
pg_restore - receiver server;
or
pd_dump - receiver server;
pg_restore - server-receiver;
pg_dump is backwards compatible not forwards.
In the explanations below Postgres versioning(major/minor) is determined as:
Pre-version 10:
X.x.x
10+:
X.x
Where X is major and x is minor.
This means if are moving forwards in Postgres major version then:
1) Use pg_dump from newer version of Postgres to dump from older version
of Postgres. In your case pg_dump(v14) dump Postgres server v12.
2) To restore use the version of pg_restore for the Postgres version you
are restoring to. In your case pg_restore(v14).
Staying on the same version:
1) Use the pg_dump/pg_restore for the version your are on.
2) If you are moving from one minor release to another then it would be
better to use the latest minor release version to get any bug fixes.
Going backwards from newer version to older version:
This is not supported.
