#5396: postgis_restore.pl keeps FUNCTION _st_concavehull(geometry)

 Priority:  medium                 |  Milestone:  PostGIS 3.4.0
Component:  build/upgrade/install  |    Version:  master

-----------------------------------+---------------------------
 I've taken a dump of a database loaded with non-extension core, topology
 and raster sql files from 3.0.9dev.
 Upon restoring it with postgis_restore.pl here's the KEEP list:
 {{{
 KEEP: FUNCTION _st_concavehull(geometry)
 KEEP: TABLEDATA layer
 KEEP: TABLEDATA topology
 KEEP: SEQUENCE_SET topology_id_seq
 }}}

 This probably means we're missing a drop of the old signature.
 The postgis.sql.in file contains a DROP of the _st_concavehull(geometry)
 function, protected by a POSTGIS_GEOS_VERSION conditional, as for older
 geos we'll have a DIFFERENT signature, making upgrades harder to handle.

 I think we should always provide the SAME signature, and internally
 complain if a parameter is passed that we cannot handle due to lack of
 GEOS.
