pgcrypto Documentation/Function Mismatch

Hello,

I wanted to pass along a pgcrypto documentation/function definition
mismatch in (at least) v9.3 and v9.6.

The mismatch occurs in the hmac function definition:

Documentation:

hmac(data bytea, key text, type text) returns bytea

As defined in 9.3.17 and 9.6.6:

                         List of functions
Schema | Name | Result data type | Argument data types |  Type 
-------+------+------------------+---------------------+--------
tools  | hmac | bytea            | bytea, bytea, text  | normal
