-----------------------------------------------------------------
[~julianhyde] I added support for WKB, EWKT, GEOJSON and GML in the following
[draft PR|https://github.com/apache/calcite/pull/2893]. I also improved the
documentation and implemented some of the unsupported functions. As some the
functions are aliases to others, to which extent should we add tests for these
in the spatial.iq file (e.g. ST_asText, ST_asWKT)? Also, in terms of
organization, should we order the functions in alphabetical order, or group
them by type (e.g. WKB, WKT, etc.). The [list of
function|https://postgis.net/docs/PostGIS_Special_Functions_Index.html] in
Postgis is rather long and I guess some conventions to keep things clear may
help as more of them get implemented.
