Client: Add PARALLEL and VOLATILE categories

+## PostgreSQL
+When adding or modifying PostgreSQL functions make sure that the
+[VOLATILITY](https://www.postgresql.org/docs/current/static/xfunc-volatility.html) and [PARALLEL](https://www.postgresql.org/docs/9.6/static/parallel-safety.html) categories are updated accordingly.
+
+Please mark public [client functions](client/sql) or [templates](client/renderer/templates)
+as STABLE even if the internals are VOLATILE to allow the planner to cache
+results inside a query. For example, in this query we need `cdb_geocode_admin1_polygon`
+to be STABLE so it gets called only once (instead of once per row):
+```sql
+SELECT * japank WHERE NOT (the_geom && cdb_geocode_admin1_polygon('Madrid', 'Spain'));
+```
+
+As PARALLEL labels need to be stripped for incompatible PostgreSQL versions,
+please use _PARALLEL SAFE/RESTRICTED/UNSAFE_ in uppercase so it's handled
+automatically.
