I can't get this to work. If I modify my function to be

CREATE FUNCTION no_accents(text)
RETURNS boolean
AS 'select $1 = unaccent($1);'
LANGUAGE sql STABLE STRICT
SET search_path = '@extschema@';

then I get

d=# create extension unaccent;
ERROR: function unaccent(text) does not exist
LINE 1: select $1 = unaccent($1);
^
HINT: No function matches the given name and argument types. You might
need to add explicit type casts.
QUERY: select $1 = unaccent($1);

If I modify it to be

CREATE FUNCTION no_accents(text)
RETURNS boolean
AS 'select $1 = unaccent($1);'
LANGUAGE sql STABLE STRICT;
ALTER FUNCTION no_accents(text) SET search_path = '@extschema@';

then I get the same restore problem I originally described.

What am I doing wrong?
