percona-toolkit does not get updated to latest update via standard repo or PERCONA repo servers:
had the PT-1673 bug for long, and tried to get latest update for pt-show-grants installed, but it kept saying 3.0.12, and there are a 3.0.13 release
PT-1673
DBD::mysql::db selectall_arrayref failed: Unknown column 'account_locked'
Then forced it to install
https://repo.percona.com/yum/release/7Server/RPMS/x86_64/percona-toolkit-3.2.0-1.el7.x86_64.rpm CWPpro version: 0.9.8.997
Distro Name: CentOS Linux release 7.8.2003 (Core)
Kernel Version: 3.10.0-1127.13.1.el7.x86_64
Platform: x86_64 vmware
MySQL version: 10.1.45-MariaDB
Now pt-show-grants report 3.2.0, and issue PT-1673 has been fixed.
