Hi Everyone, We’re trying to solve a problem that relies on BigSerial and txid (as returned by txid_current() ) values being issued consistently.
Is it possible for two transactions to interleave their issuance of these two variables? For example: Schema: CREATE TABLE EXAMPLE( offset bigint PRIMARY KEY GENERATED BY DEFAULT AS IDENTITY NOT NULL, txid BIGINT NOT NULL DEFAULT 1 ); Insert statement: "INSERT INTO EVENTS (txid) VALUES (txid_current());"; Prior to transactions executing offset is 10 and txid is 1000. Transaction 1 and 2 occur concurrently. Is it possible for transaction 1 to be issued txid 1001 and offset 12 and transaction 2 to be issued txid 1002 and offset 11? Any help would be much appreciated. Regards, Adam This is a confidential email. Tesco may monitor and record all emails. The views expressed in this email are those of the sender and not Tesco.
