I would like to dump the whole schema in ONLY mode, including table
data for only that schema, excluding data for child tables in other
schemas.
Why would they be locked then?
Which part of pg_dump requires locking child tables?
Per the docs, "COPY only deals with the specific table named; it does
not copy data to or from child tables. "
I just want to understand why there is LOCK TABLE not LOCK TABLE ONLY.
