from psql console you can use a \df command

[pavel@pavel-stehule ~]$ psql postgres
psql:/home/pavel/.psqlrc:4: \pset: unknown option: linestyle
Output format is wrapped.
psql (8.4.8, server 9.2devel)
WARNING: psql version 8.4, server version 9.2.
         Some psql features might not work.
Type "help" for help.

postgres=# \df
                              List of functions
 Schema |       Name        | Result data type | Argument data types |  Type
--------+-------------------+------------------+---------------------+--------
 public | getdaigtest_raise | void             |                     | normal
 public | getdiagtest       | void             |                     | normal
 public | getdiagtest_raise | void             |                     | normal

postgres=#

\dfS show a system functions - you can use a wild chars

postgres=# \dfS *agg
                            List of functions
   Schema   |    Name    | Result data type | Argument data types | Type
------------+------------+------------------+---------------------+------
 pg_catalog | array_agg  | anyarray         | anyelement          | agg
 pg_catalog | string_agg | text             | text, text          | agg
 pg_catalog | xmlagg     | xml              | xml                 | agg
(3 rows)

you can you a extended view via symbol plus

postgres=# \dfS+ *agg
