FYI I intend to get the ModifyTable split patch (0001+0003) pushed hopefully on Tuesday or Wednesday next week, unless something really ugly is found on it.
As for MERGE proper, I'm aiming at getting that one pushed on the week starting March 21st, though of course I'll spend some more time on it and will probably post further versions of it before that. -- Álvaro Herrera PostgreSQL Developer — https://www.EnterpriseDB.com/ Thou shalt check the array bounds of all strings (indeed, all arrays), for surely where thou typest "foo" someone someday shall type "supercalifragilisticexpialidocious" (5th Commandment for C programmers)
