- gram-only.diff (text/plain) patch
Hi, does your patch still work if you make ONLY a ColLabel and not a TokenId, this would lead to ONLY not being a ColId and by that removing all unresolvable conflicts in the grammar? This patch against your gram.y does this. I have tested it with bison 1.27, and verified that the conflicts are gone, but I have not tested it for correct behavior in postgres. I did not have the time to understand the whole grammar so I might have missed something obvious.
