dba_handlers() list all the handlers supported by this extension.
full_infoTurns on/off full information display in the result.
Returns an array of database handlers. If full_info
is set to true, the array will be associative with the handlers names as
keys, and their version information as value. Otherwise, the result will be
an indexed array of handlers names.

When the internal cdb library is used you will see
cdbandcdb_make.
