This is normal.

Don't worry about them, they'll be cleaned out on re-use. What you need
to find is the system catalog corruption that is causing memory bloat
during a CREATE TABLE. Does a SELECT * FROM pg_class show any problem?
How about pg_attribute and pg_type? If plain SELECT is OK then the
issue is likely index corruption, which you could fix with REINDEX.
