Subject: [PATCH] Give the comparison families a one-letter portable prefix
 (tEq/eEq/aEq)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The temporal/ever/always comparison operators take a one-letter prefix —
t (temporal), e (ever), a (always) — over the spelled-out temp/ever/always,
matching the operator-family abbreviation the bindings already use (eIntersects
is the ever- form) and the MEOS C prefixes (teq_/eeq_/aeq_). So:

  #= #<> #< #<= #> #>=   ->  tEq tNe tLt tLe tGt tGe
  ?= ?<> ?< ?<= ?> ?>=   ->  eEq eNe eLt eLe eGt eGe
  %= %<> %< %<= %> %>=   ->  aEq aNe aLt aLe aGt aGe

Also spell the distance bare name tDistance (camelCase), matching the canonical
tgeo @sqlfn spelling, so the portable dialect and the catalog agree on one
case-sensitive name (a binding engine that folds case otherwise shadows one
spelling with the other).
