Does it matter if this function runs on the server side or in the
client?

How are field boundaries recognized? By column position? By
patterns in the content? This might be easiest with a language
like Perl, Python, Tcl, etc., whether on the client side or in a
server-side function written in one of those languages (PL/Perl,
PL/Python, PL/Tcl, etc.). You could do it with SQL but other
languages are more suitable for text parsing.
