We certainly can't extend the regular CREATE SEQUENCE command this way; you can't create shared objects after initdb. The "clean" way to handle this would be to extend the bootstrap command parser to accept a command along the lines of CREATE [SHARED] SEQUENCE and then add a file in src/include/catalog that defines the shared user-id-generator sequence. (Look at how pg_shadow is created for precedent.) Not having looked recently, I have no idea how much pain is implied by the preceding paragraph ;-). I'd be willing to accept cruder compromises if that approach seems impractical, but please look to see if it can be done nicely first. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
