Allow configuring datastore full text field indexes with new
ckan.datastore.default_fts_index_field_types config option.
The default is “text tsvector” but this can be changed to
“” to avoiding automatically creating separate full text indexes
for any individual columns. This will result in a significant reduction

exists for all tables.
After upgrading to CKAN 2.12 the default changes to “”.
Use the ckan datastore fts-index command to remove existing
column indexes to reclaim database space. (#5847
