Bug reference:      1571
Logged by:          CaT
Email address:      cat@zip.com.au
PostgreSQL version: 7.4.7
Operating system:   Linux (Debian woody with backports.org pgsql)
Description:        Cannot grant execute functions to non-superusers
Details:

Basically, I just cannot get my nonsuperuser access to the functions I
import. Aparently this works for 8.0 but I'm using 7.4.7 and its gone all
wibbly.


CREATE OR REPLACE FUNCTION gen_salt(text) RETURNS text AS
'$libdir/pgcrypto', 'pg_gen_salt' LANGUAGE 'C';
...
postgres=# \df+ gen_salt
                                                  List of functions

Ok. I apparently misunderstood something. It seems you can't add global
functions and just give users access to them. You need to dupe functions
on a per db basis. So... feel free to move along and ignore this bug
report. :)

Nothing to see here... :)

This is not a permissions problem, it's a "you're not looking in the
right place" problem.  I speculate that either you loaded the functions
in the wrong database, or holly for some reason doesn't have the public
schema in her search path.

Yes. Definately a PEBCAK issue. :)
