Not sure what your #s are saying. Does that mean that myschema output
400,000 tables out of 2,500,000 tables?

I actually have an AWK script to post process the schema output and break
up the indexes into separate files by table. Not hard to write so there's
not much internal pressure to make it an enhancement to myschema. It
wouldn't be hard. Just close the current output file and open a new one
when a new table starts. That would put each table and its indexes and
triggers into separate files. Then it could switch to the common file for
everything else: functions, procedures, UDTs, and constraints that are
normally ganged at the beginning and end of the schema file.
