Thread: Lock compatibility matrix
I had this in a different form, but reworked so that it matches the doc patch that Teodor submitted earlier. I think it would be good to have this information in the lock.h file as well.
Thanks,
Pavan

so I may be wrong here.

The lock information is not available anywhere in the form of a matrix. I've personally found a matrix useful for application design, though that hasn't influenced Pavan's independent creation of exactly that. -- Simon Riggs EnterpriseDB http://www.enterprisedb.com

Sure, but at this point we have proposals for adding two different matrix
representations, both redundant with the textual description. I don't
mind adding one of the two, but both seems overkill.

A patch for the documentation has been proposed. Cool. When that's done, we probably don't need the code version. Would've been helpful if you'd explained what you meant... not many people read all posts on all lists. -- Simon Riggs EnterpriseDB http://www.enterprisedb.com

Docs patch is in SGML table representation, text view is a demonstration in mail.
