> The EPSG factory works as expected on Derby. But attempt to use the factory on PostgreSQL
sometime produces the following error message:
> {noformat}
> ERROR: operator does not exist: epsg."CRS Kind" ~~ unknown
> SQL state: 42883
> Hint: No operator matches the given name and argument type(s). You might need to add
explicit type casts.
> {noformat}
> The issue occurs in expressions like {{coord_ref_sys_kind LIKE 'projected%'}} with the
{{coord_ref_sys_kind}} column defined as an enum when Apache SIS is using PostgreSQL. The
fix is to cast the {{CRS Kind}} enum to {{VARCHAR(24)}}. The bug does not happen in Derby
because that column is already a {{VARCHAR(24)}} since Derby does not support enums.
