Previously, the PostgreSQL agent plugin mk_postgres failed to detect older EnterpriseDB (EDB) instances on Linux. These older EDB versions use edb-postmaster as the process name instead of the newer edb-postgres. As a result, those instances were silently ignored and no PostgreSQL monitoring data was collected for them.

This has been fixed. The plugin now correctly identifies both edb-postgres and edb-postmaster processes on Linux.
