The section on SQL keywords in the User's Guide needs some updating.
I figured that I could generate these various lists of reserved and
non-reserved keywords automatically --- and indeed I can!
But now I've got 36 lists of keywords (all the set differences between
SQL92 reserved/non-reserved, SQL99 reserved/non-reserved, PG
reserved/non-reserved (which is a simplification)) -- none of which are
empty (some keywords where dropped from reserved to non-reserved between
SQL92 and 99) -- but that's more than anyone wants to know.
But does anyone know what they do want to know?
The list of PostgreSQL reserved words seems to be the only thing I can see
as definitely essential. But which is more important: The list of words
that are reserved in PG but *not* reserved in SQLxx (i.e., what problems
can I expect when porting stuff to PG), or the opposite (i.e., what words
should I avoid when writing portable SQL).
