Robert Haas cff440d368 pg_stat_statements: Widen query IDs from 32 bits to 64 bits. ... This takes advantage of the infrastructure introduced by commit 81c5e46c49 to greatly reduce the likelihood that two different queries will end up with the same query ID. It's still possible, of course, but whereas before it the chances of a collision reached 25% around 50,000 queries, it will now take more than 3 billion queries. Backward incompatibility: Because the type exposed at the SQL level is int8, users may now see negative query IDs in the pg_stat_statements view (and also, query IDs more than 4 billion, which was the old limit). Patch by me, reviewed by Michael Paquier and Peter Geoghegan. Discussion: http://postgr.es/m/CA+TgmobG_Kp4cBKFmsznUAaM1GWW6hhRNiZC0KjRMOOeYnz5Yw@mail.gmail.com		2017-10-11 19:52:46 -04:00
