I'm creating my own parser/regex combination for fast and lightweight Postgres queries processing (in a user app). So I wanted to double check some details in PG source, but could not find the geometric operators (http://www.postgresql.org/docs/8.4/static/functions-geometry.html) definition/rules neither in gram.y nor in scan.l.
I could try to define the rules based on documentation... but would it be possible to find how they are defined in the PG source?
