PQescapeLiteral(), PQescapeIdentifier() documented with invalid signatures.

Actual signatures of libpq's functions PQescapeLiteral(),
PQescapeIdentifier()
is
char *PQescapeLiteral(PGconn *conn, const char *str, size_t len)
char *PQescapeIdentifier(PGconn *conn, const char *str, size_t len)

that differs from signatures provided in the documentation here
http://www.postgresql.org/docs/9.0/static/libpq-exec.html#LIBPQ-EXEC-ESCAPE-STRING

Wow ... I can understand missing the "const" declarations, but getting
the return type wrong is pretty bad :-(. Amazing nobody caught this
before. Thanks, will fix!
