PFA the updated version of the patch made fully compatible with changes in v13 and I suppose it is ready to be reviewed for v14.
Main things changed: 1. Patch is made compatible with new lists representation ( 1cff1b95ab6d ) 2. Patch is made compatible with the incremental sort ( d2d8a229bc58 and ba3e76cc571e ) 3. Tests are changed to represent changes in keys numbering and naming convention in the plan ( 55a1954da16 and 6ef77cf46e8 ) As always your ideas are very much welcome! -- Best regards, Pavel Borisov Postgres Professional: http://postgrespro.com <http://www.postgrespro.com>
