Why do you want to avoid this? It may be the only option you have, other
than a database dump and reload.

This seems odd. I would have thought for sure that it was your indexes
growing. Maybe you should try looking at the individual files in the
data directory to see which ones are growing, and then use the filename
to look up the item in pg_class via the relfilenode column to find out
what your problem objects are.

It means you haven't done an ANALYZE after changing the size of the
database.
