We are using the pg_indexes view (indexdef) to retrieve the index definition.
Are you saying that as a normal part of building an index, there are short periods of time where the pg_indexes view will show the index with ON ONLY specified?

What do you mean "somehow changed"? There is nothing in the system
catalogs that stores that exact string, so I suppose what you mean
is that some tool is presenting the indexes to you that way.
If that tool is pg_dump, this is its normal behavior. There will
be other commands in its output that build the rest of the
partitioned index set.
