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
