While I agree with John and write 98% of my functions in plpsql I found
it necessary to write a couple of functions in Perl because I had to
parse a text field that was sufficiently complex as to almost completely
rule out plpsql.

You will need to focus your learning on whatever makes sense for the
majority of your application.  The good news is that plpsql comes almost
for free so you still get one more. ;-)
