It is my understanding that the answer is no. This is
because pl/pgSQL is a language (if configured) to be
available to all users and access to external
routines,
the filesystem, etc. would be a major security hole,
since each backend runs as user 'postgres'. That's
why Postgres superuser privileges are necessary to
create functions in a language like 'C':
"Only users with Postgres superuser privilege are
permitted to create a function in the 'C' language.
Others may use the 'sql' language or the
created procedural languages."
Hope that helps,
