1) Short version
Short version bytea fields != large objects.
2) Long version
From here:
https://www.postgresql.org/docs/current/app-pgdump.html
<https://www.postgresql.org/docs/current/app-pgdump.html>
-B
--no-large-objects
--no-blobs (deprecated)
Exclude large objects in the dump.
When both -b and -B are given, the behavior is to output large
objects, when data is being dumped, see the -b documentation.
Where large objects are defined here:
https://www.postgresql.org/docs/current/largeobjects.html
