Description:
On this page I read this:
https://www.postgresql.org/docs/current/functions-matching.html
> If you have pattern matching needs that go beyond this, consider writing a
user-defined function in Perl or Tcl.
I think Perl and Tcl are no more the most common languages to write
user-defined functions.
Maybe just remove "in Perl or Tcl" and provide a link to the general docs of
user-defined functions.
