That was a seriously bad idea.
The problem that you now have is that pg_class.relowner is out of sync
with the ownership data in pg_shdepend. As Alvaro said, it's also going
to be out of sync with pg_class.relacl, if any of those tables had
explicit GRANTs.
REASSIGN OWNED, by itself, will not fix this situation since it relies on
pg_class.relowner to decide which objects need to be reassigned. What you
need to do is undo that manual catalog hacking and then use REASSIGN OWNED
to get to where you wanted to be.
If you don't remember exactly which tables you changed manually, you could
probably do a join against pg_shdepend to find them: look for tables that
have a matching pg_shdepend row but the relowner doesn't match the
refobjid.
