Returning []byte results in server (postgres) crashes and generates incorrect SQL

[onshorechet]

Writing a go function that returns []byte will generate a sql header like:

CREATE OR REPLACE FUNCTION CompressGzip(data text,level bigint)
RETURNS [] AS
'$libdir/vl', 'CompressGzip'
LANGUAGE c VOLATILE STRICT;

From this go function:

func CompressGzip(data string, level int) []byte {
        return cGzip([]byte(data), level);
}

Amending that sql header and installing the function will result in a server crash on use of the function.

I take a look at it.
