There are two different questions here.
1. Reads are not blocked in PostgreSQL by writers, even if another transaction has updated the row but not yet
committed.
2. There is no equivalent of a dirty read in PostgreSQL. You can only read committed data (short of bypassing the
databaseand reading the disk directly).
