Hi! Greetings from OSGeo Code sprint in Minneapolis :)
We're trying to make FULL JOIN on equality of geometry and can't figure out why it doesn't work. Here's reproducer, it works on bytea but not on PostGIS geometry throwing out ERROR: FULL JOIN is only supported with merge-joinable or hash-joinable join conditions https://trac.osgeo.org/postgis/ticket/4394 We already have a btree opclass with equality: https://github.com/postgis/postgis/blob/svn-trunk/postgis/postgis.sql.in#L420 We also have hash equality opclass: https://github.com/postgis/postgis/blob/svn-trunk/postgis/postgis.sql.in#L440 Reading through Postgres documentation I can't figure out what else shall we do for this join to work. How do we make it work? -- Darafei Praliaskouski Support me: http://patreon.com/komzpa
