You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: wal_reader.rs
    path of file: ./repos/readyset/replicators/src/postgres_connector
    
    the code of the file until where you have to start completion: use std::collections::{HashMap, HashSet};
use std::convert::TryInto;
use std::sync::Arc;

use replication_offset::postgres::{CommitLsn, Lsn};
use rust_decimal::prelude::FromStr;
use rust_decimal::Decimal;
use tokio_postgres as pgsql;
use tracing::{debug, error, trace};

use super::wal::{self, RelationMapping, WalData, WalError, WalRecord};
use crate::postgres_connector::wal::{TableErrorKind, TupleEntry};

                    schema,
