I am new to the mailing list, but not new to postgres. I did search through the mail-list archives, and didn't find an answer to this question. Oracle has a concept of a "globally unique ID" which can be gotten from their function call SYS_GUID(). Is there any plan to implement this (or something analogous) in a future version of Postgres? -- Keith Rose (ext. 2144) ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
