[postgis-users] Wrong format: PostGIS misses a " " in it's WKT output?

[Rémi c]

Hey Paul, great to hear from you!
Yeah I agree this is a bit confusing :-/

The standards are here <https://www.ogc.org/standards/sfa#downloads>, page
54.
The interesting line is ```<polygon tagged text> ::= polygon <polygon text>
```
Where `<polygon text>` is then refined into EMPTY or a list of linestrings
between parenthesis.

It looks like the python lib Shapely enforces the space.
Not sure what to do here, I'd like to follow the standard,
but the PostGIS is kind of the standard way to follow the standard.

Remi
