Hi, Today I hit "ERROR: target lists can have at most 1664 entries", and I was surprised the limit was not documented.
I suggest that the limit of "1664 columns per tuple" (or whatever is the right term) should be added to the list at https://www.postgresql.org/docs/current/limits.html e.g. after "columns per table". Could someone please commit that 1-2 line doc improvement or do you need a patch for it? Vladimir
