TYPO3 Core

Given the following definition in ext_tables.sql the Install Tool wants to re-create the index every time a database compare is being performed.

#
# Table structure for tables 'tx_sitelist_domain_model_zipcode'
#
CREATE TABLE tx_spatial_domain_model_zipcode (
  zipcode varchar(16) DEFAULT '' NOT NULL,
  place varchar(255) DEFAULT '' NOT NULL,
  location point DEFAULT '' NOT NULL,

  KEY zipcode (zipcode),
  SPATIAL KEY location (location)
) ENGINE=MyISAM;

1. An existing index is not being detected properly (wrong/unknown) type, this leads to being offered to drop existing index as well as creating the new index
2. Re-creating the index after database compare leads to duplicate index errors, it seems dropping the existing index would be performed after the new index has been created
