Dear sir, 

I'm using the citext datatype in my application. I have PostgresSql 9.6 installed by EnterpriseDB

psql mydatabase postgres

create extension citext with schema myschema

\c mydatabase biguser

set search_path to myschema;

create table tst(v citext);

insert into tst values('sadek');

> select strpos(v, 'd') from tst;

ERROR:  permission denied for function strpos

> select strpos(v, 'd'::citext) from tst; (If I read the documentation correctly this should work! alas, it doesn't)

ERROR:  permission denied for function strpos

> select strpos(v::citext, 'd'::citext) from tst;

ERROR:  permission denied for function strpos

> select strpos(v::citext, 'd') from tst;

ERROR:  permission denied for function strpos

> select strpos(v::citext, 'd'::citext) from tst;

Am I missing something here?
