In Postgres 11, according to documentation, txid_current() should return biginteger but I'm getting small integer that doesn't look like is extended by epoch counter. My txid looks like this: 1123
"The internal transaction ID type (xid) is 32 bits wide and wraps around every 4 billion transactions. However, these functions export a 64-bit format that is extended with an “epoch” counter so it will not wrap around during the life of an installation."
Am I interpreting documentation incorrectly?
