Thanks for your reply, I have added some SQL statements, such as the following example when I use the BIT or BIT VARYING type, similar problems will occur.
postgres=# CREATE TABLE t(c BIT varying(10)) PARTITION BY HASH((t.c)); ERROR: data type bit varying has no default operator class for access method "hash"
postgres=# CREATE TABLE t(c BIT) PARTITION BY HASH((t.c)); ERROR: data type bit has no default operator class for access method "hash"

cdbhash_float8_ops seems specific to Greenplum, so not found in community Postgres.
