TYPO3 Core

Using the `DB Check` -> `Full Search` to do a text fullsearch accross the full database
is inoperable and broken if PostgresSQL is used as dbms.

This boilds down to type conversion issues and applying 'like' string searches against
non text compatible field (types).

For example, with installed ext:styleguide and created records, you could search for
`styleguide demo group 1` as a test.

That's the same acceptance test would test, which is currently not active and not activatable
using PostgresSQL.
