BUG #15282: Materialized view with transitive TYPE dependency failsrefresh using pg_restore and psql

The following bug has been logged on the website:

Bug reference:      15282
Logged by:          Keith Hickey
Email address:      kwhickey@gmail.com
PostgreSQL version: 10.4
Operating system:   RHEL7, Mac OSX
Description:

Scenario:
A materialized view runs a select query that uses a function on one of its
projected columns which internally uses an enum TYPE to map the column value
to an enum value.

Action and Resulting Error:
Trying to restore a database setup in the above way will fail with error:
ERROR:  type "<type_name>" does not exist

Reproduction:
This can be reproduced with a "plain" (.sql) dump of the database using
pg_dump and then restoring the schema and data by running psql against that
dump. It can also be reproduced when using a pg_dump --format=directory dump
of the database, and restoring that dump using pg_restore.

Failed Workarounds:
Lots of things, that didn't work.
(1) using --list to create a file to use with pg_restore and --use-list that
excluded MATERIALIZED VIEW DATA initially. Then doing this again to include
only MATERIALIZED VIEW DATA in a 2nd pg_restore call. It still resulted in
the same error.
(2) Doing the same as above but excluding MATERIALIZED VIEW (create) and
MATERIALIZED VIEW DATA statements initially, and then running only those in
a 2nd pg_restore call
(3) Doing the same as above, creating the database manually, then using
pg_restore --list / --use-list to create only TYPES, then calling pg_restore
to do everything but MATERIALIZED VIEW DATA, then finally using pg_restore
to do MATERIALIZED VIEW DATA only. Same result. Also separating out the
functions did not help either.
(4) Doing pg_restore in 3 phases using the --section flag: run once with
--section=pre-data, a second time with --section=data, a third time with
--section=post-data. Failed the 3rd time with the same error.
(5) Setting up default privileges in the database to GRANT ALL PRIVILEGES on
all objects (including TYPEs) before running pg_restore. 
(6) Restoring a plain sql dump of the database with psql. This failed so
long as the REFRESH MATERIALIZED VIEW call was in the same psql invocation
as the TYPE creation.

Successful Workaround:
Exclude the MATERIALIZED VIEW DATA entries from the pg_restore, do the
pg_restore, then follow that with a psql call to REFRESH each materialized
view

"But the issue is that CREATE MATERIALIZED VIEW ... WITH NO DATA
tries to plan and execute the query, not just store it, which entirely
defeats pg_dump's attempt to avoid hidden dependencies.  We need a less
chintzy solution to handling this variant of CREATE MATERIALIZED VIEW."
