Обсуждение: pgsql: Make geometry cast functions error safe
Make geometry cast functions error safe This adjusts cast functions of the geometry types to support soft errors. This requires refactoring of various helper functions to support error contexts. Also make the float8 to float4 cast error safe. It requires some of the same helper functions. This is in preparation for a future feature where conversion errors in casts can be caught. (The function casting type circle to type polygon is not yet made error safe, because it is an SQL language function.)
