Thank you Francisco, that's a clever idea. However, I don't think this would
reduce the complexity since the target pattern can contain
1) regular back-references (referencing to matches of its own)
2) the special source text references I mentioned
Obviously, these will have to be written in a different way and this I
believe brings me back to start (or in other words, it's not a silver bullet
obviating the need to rewrite the target pattern manually).
I will probably end up writing a function in PL/Perl which Tom Lane
suggested since I'm apparently not skilled in SQL enough to be able to do it
using a single query without using custom functions.
