Standard REGEX functions

[Vik Fearing]

The standard uses XQuery regular expressions, which I believe are subtly 
different from ours.  Because of that, I had been hesitant to add some 
standard functions to our library such as <regex occurrences function>.

While looking at commit 6424337073589476303b10f6d7cc74f501b8d9d7 from 
last year (which will come up soon from somebody else for a different 
reason), I noticed that we added those functions for Oracle 
compatibility even though the regexp language was not the same.

Are there any objections to me writing a patch to add SQL Standard 
regular expression functions even though they call for XQuery and we 
would use our own language?
