> Is there a reason for not putting your new code itself into regexp.c? Not really, I just figured it would be cleaner/easier to write it as an extension. I also figure that it is unlikely that every regexp function that anyone could possibly want will be implemented in core in that one file. If anyone writes an extension like this, they would need to duplicate a good amount of code in order to do so, that would make more difficulty in maintaining the code if it should need to change. It also makes developing a new function a lot easier, no need to re-initdb to add the function, no need to relink the postmaster and restart it every time the function changes. Anyway, the particular thing I was writing was a function like substring(str FROM pattern) which instead of returning just the first match group, would return an array of text containing all of the match groups. I exported the functions in my sandbox, and wrote a module with a function that does this. > > regards, tom lane > > ---------------------------(end of broadcast)--------------------------- > TIP 4: Have you searched our list archives? > > http://archives.postgresql.org > > -- Calling J-Man Kink.
