Manual workaround for database dumps "DEFINER" issue.

gistfile1.yml

           # Because of these issues:
           #  - https://stackoverflow.com/a/44015870/292408
           #  - https://www.drupal.org/project/workflow_participants/issues/3073354
           # A second time because the export has the issue too.
         - name: Add this function to /var/aegir/.drush/va.drush.inc
           function drush_va_post_sql_dump() {
           // BACKEND_RESULT is the full path to the file.
           $file_ext_gz = drush_get_context('BACKEND_RESULT');
           shell_exec("gunzip $file_ext_gz");
           $file_ext_sql = str_replace('.gz', '', $file_ext_gz);
           $CMD = <<<CMD
           sed 's/\sDEFINER="[^`]*"@"[^`]*"//g' -i $file_ext_sql
           CMD;
           shell_exec($CMD);
           shell_exec("gzip $file_ext_sql");
           drush_log('SQL Dump was ungzipped, DEFINER string stripped and gzipped again.', 'notice');
           }

Something todo with RDS? 🗡️

Yeah, the Drupal Workflow Participants module somehow introduced this issue (couldn't find it in source code search), I posted here about it https://www.drupal.org/project/workflow_participants/issues/3073354.
