Hi, A recent discussion in Slashdot brought up the topic of PostgreSQL's 32-bit TXID system: http://slashdot.org/comments.pl?sid=5725497&cid=47942637 I did a quick search and noticed that 8 years ago, a Skype employee provided a patch for migrating to a 64-bit TXID: http://postgresql.1045698.n5.nabble.com/RFC-txid-module-for-64-bit-external-transaction-IDs-tt1947503.html The conversation seemed to die there (I couldn't find any follow-up). If I were Facebook (which clearly I am not) should I be worried about this sort of thing? And out of curiosity, why didn't PostgreSQL migrate to a 64-bit value?
