TYPO3 Core

When using TYPO3 8.7 on PostgreSQL/PostGIS and having a geometry column on a table registered in TCA leads to

Uncaught TYPO3 Exception
Unknown database type geometry requested, Doctrine\DBAL\Platforms\PostgreSQL92Platform may not support it.

Doctrine\DBAL\DBALException thrown in file

Having table columns Doctrine\DBAL does not recognize must not lead to a completely unusable Install tool.

How to reproduce:

ALTER TABLE tx_myextension_mytable ADD COLUMN koordinate geometry(Point,3857);
