Quoting Chris Withers <ch...@withers.org>:
Hi,
I'm upgrading a database from 9.4 to 11.5 by dumping from the old
cluster and loading into the new cluster.
The database is tiny: around 2.3G, but importing this table is
proving problematic:
Column | Type | Modifiers
...
I feel like asking what I'm doing wrong here? The new server is
pretty decent hardware...
Concrete questions:
- what, if anything, am I getting badly wrong here?
- what can I do to speed up creation of this index?
- failing that, what can I do to import and then create the index in
the background?
As you can imagine, a 15hr outage for an upgrade has not met with
large amounts of happiness from the people whose application it is
;-)

Hi Chris,
This sounds like a candidate for pg_logical replicating from the old
to new system.
