Doc: de-document unimplemented geometric operators.

tglsfdc · tglsfdc · commit 922b23c13be0 · 2021-12-13T17:49:36.000-05:00
In commit 791090b, I made an effort to fill in documentation for all geometric operators listed in pg_operator. However, it now appears that at least some of the omissions may have been intentional, because some of those operator entries point at unimplemented stub functions. Remove those from the docs again. (In HEAD, poly_distance stays, because c5c192d just added an implementation for it.) Per complaint from Anton Voloshin. Discussion: https://postgr.es/m/3426566.1638832718@sss.pgh.pa.us
