TBH, I'm suspecting pilot error.  I wonder whether you have another
table by the same name in a different schema, which is the one
containing the "corrupted" rows, and after you rename this table
out of the way you're unintentionally accessing the other one.

That theory doesn't explain the rows surviving TRUNCATE, but
maybe inheritance could --- IIRC, TRUNCATE will not touch child
tables.  So maybe the alias table is also an inheritance child
of the one you are modifying?

This command in psql would clarify much:

postgres=# \d+ *."NCAASchedule"
