I do not see that as possible. Something ran CREATE OPERATOR FAMILY:
pg_restore: [archiver (db)] could not execute query: ERROR: operator
family "gin__int_ops" for access method "gin" already exists
Command was: CREATE OPERATOR FAMILY gin__int_ops USING gin;
So either someone opened up template0 and loaded the extension into it
or the dump file has the CREATE OPERATOR FAMILY in it. Another thought
search on intarray.

We are not dealing with magic here, there is some mechanism at work.
Dollars to donuts there is an unpackaged version of the extension in one
or more of the source databases. See below for more information on this:
https://www.postgresql.org/docs/11/extend-extensions.html
38.16.5. Extension Updates
You will need to look at the source databases in situ.
