Didn't work how, exactly? I don't know much Python but I'd think you
have a quote-nesting mistake there. And anyway, shouldn't it be single
quotes in the SQL command, ie

return plpy.execute("select getcountrycode('9821788')",1)

which you actually need to write as

return plpy.execute("select getcountrycode(\'9821788\')",1)

because you're already inside a single-quoted string.

Dunno; it is certainly possible that pgAdmin isn't careful about
preserving leading indentation. I'd suggest taking that up with the
pgAdmin guys; I'm sure they'll fix it when you point out that python
is picky about this.
