Tip
If you have pattern matching needs that go beyond this, consider writing a
user-defined function in Perl or Tcl.
```
I think Perl or Tcl are not the common choice today.
AFAIK Python is quite popular, and they have a good regex implementationd,
too.

If Python had a trusted PL variant, I'd be happy to recommend that here.
But as long as we only have plpythonu, it's pretty hard to recommend
it for run-of-the-mill tasks like pattern matching.
(The lack of plain plpython isn't our fault; it's that Python has
no sandboxing mechanism.)
