Review Comment:
Fixed in 15cc146da02: the tolerance type documentation now includes int,
matching the function signature.

+# ST_EqualsExact
+
+Introduction: Return true if A and B have the same structure and their
corresponding coordinates are equal within a tolerance.
+
+Unlike `ST_Equals`, this predicate requires geometry types, component order,
ring order, and vertex order to match. The tolerance is the maximum distance
allowed between each pair of corresponding coordinates. The comparison uses x
and y coordinates and ignores z and m coordinates.
Review Comment:
Fixed in 15cc146da02: changed the introduction to use Returns true and
capitalized Z and M.
