{ oid => '111', array_type_oid => '6099', descr => 'similarity columns', typname => 'similarity_columns', typlen => '-1', typlen => '-1', typbyval => 'f', typcategory => 'U', typinput => 'byteain', typoutput => 'byteaout', typreceive => 'bytearecv', typsend => 'byteasend', typalign => 'i', typstorage => 'x' }, I add above into pg_type.dat. And then I add execute “make install” and restart pg. And Then do below: postgres=# SELECT typname from pg_type where typname like '%similarity%'; typname --------- (0 rows) I can’t get the type I added. What else I need to do?
