I changed my code to use position() instead of textpos(), the only
problem is that I now get a parse error at the following line:

    i:= position(stringa, ',');

The exact error message is:

ERROR: parser: parse error at or near ","

Trying to run a query like, 'select position(email, ',') from table'
fails with the same parse error, however 'select strpos(email, ',') from
table' runs fine...

any hints?
