Understanding PostgreSQL Timestamp Data Types, When you query timestamptz from the database PostgreSQL converts the UTC value back to the time value of the timezone set by the database server the user or the current database connection Notice that both timestamp and timestamptz uses 8 bytes for storing the timestamp values as shown in the following query
