After upgrading to 6.2.2 i've got multiple perl DBI errors like this
Can't use an undefined value as an ARRAY reference at /usr/local/lib/x86_64-linux-gnu/perl/5.28.1/DBI.pm line 2086.
On 2086 string driver works with column names
( DBI.pm )
May this error depends on this update
Downgrading to 6.2.1 solves the problem.
