New version 0.1.5 is released in the unstable area and here is the ChangeLog:

  • Add basic Firebird version detection to ensure that only functions available on the remote Firebird server are actually pushed down
  • Push down functions COALESCE(), NULLIF()
  • Only push down SUBSTRING() if 2nd and 3rd arguments are INTs

Also fbsql is progressing (a command-line client for Firebird inspired by PostgreSQL’s psql)
