Comment (by pramsey):

 Passing the output through `ST_MakeValid(geom, 'method=structure')` or
 `ST_MakeValid(geom, 'method=linework')` is something you can do now. If
 the actual `ST_Polygon` function is failing, that's a different problem
 entirely, and looking at
 [https://github.com/postgis/postgis/pull/674/files GH674] not a problem
 that was introduced when the validity checks were removed. I'd rather you
 just wrap your function in ST_MakeValid than add a flag that just does the
 exact same thing.
