Hello.

Browse Source 
The following patch extends the COMMENT ON functionality to the
rest of the database objects beyond just tables, columns, and views. The
grammer of the COMMENT ON statement now looks like:

COMMENT ON [
  [ DATABASE | INDEX | RULE | SEQUENCE | TABLE | TYPE | VIEW ] <objname>
|

  COLUMN <relation>.<attribute> |
  AGGREGATE <aggname> <aggtype> |
  FUNCTION <funcname> (arg1, arg2, ...) |
  OPERATOR <op> (leftoperand_typ rightoperand_typ) |
  TRIGGER <triggername> ON relname>
