This seems quite restrictive, especially considering the WKT standard does not prescribe a specific maximum length. In fact, it recommends a maximum of 4096 characters for CRS WKT strings. The current limit is therefore only half of what the standard suggests as a recommended maximum.

This is a direct copy from the OGC spec, I am pretty sure, and I don’t think there’s any reason we could not use the PgSQL ’text’ type instead.

That said, we haven’t had any issues with running out of space so far, 24 years in.
