Re: pg_get_serial_sequence is inconsistent

FYI, we have at least documented this behavior in 8.2.X:

   <function>pg_get_serial_sequence</function> returns the name of the
   sequence associated with a column, or NULL if no sequence is associated
   with the column.  The first input parameter is a table name with
   optional schema, and the second parameter is a column name.  Because
   the first parameter is potentially a schema and table, it is not treated
   as a double-quoted identifier, meaning it is lowercased by default,
   while the second parameter, being just a column name, is treated as
   double-quoted and has its case preserved.  The function returns a value
