I'm an experienced oracle DBA since 2004, starting 9i ~ 12c.

Starting as PostgreSQL DBA since 2010: - create a small module to communicate to core banking system (plpgsql + php) - Manage own replication from oracle to PostgreSQL - Manage database maintenance (280+ databases) - Manage multimaster replication (BDR) - consolidation from 280+ database/servers into single server - Troubleshoot performance problem for ETL processes - Benchmark Postgresql BDR to choose the better linux kernel for mutex overhead issues
