SQL:2011 Valid-Time Support

2018-05-08 Thread Paul Howells
Hello All,

I am sure this has been discussed somewhere but I have not found anything
specific in the archives.

Has there been or is there any current effort to implement SQL:2011
valid-time support in Postgres?  I understand that there has been some
efforts to implement some valid-time support but now that there is a
published standard I think that it would be valuable to try to obtain some
level of compatibility.   Is this something the community has decided
against?

Ultimately I am wondering if this is something that would be worth me
spending my time on.

Thanks
Paul


Adding a new table to the system catalog

2018-05-26 Thread Paul Howells
Hello All,

I am exploring and poking at the source code to inform a design for adding
valid-time support to postgres.  The feature will required updating
existing system catalog tables as well as adding one or more new tables.

Is there any documentation on how to update the system catalog?  What files
need to be created/updated?  Do I need to run any utilities for generation
manually or is this done as part of the build?  How do I assign a new OID?

Thanks in advance
Paul
