PostgreSQL allows you to customize statement logging in numerous ways. You can globally set the level of logging you want at both the postgresql.conf (that will affect all databases) or at the database level using the various log_statement* variables. Most of these
are documented in runtime config logging.
For this brief article, we'll talk about the log_line_prefix variable. By default this variable is very minimalistic and just prefixes the log lines with the date time of the statement. If you have just one database (like the way Oracle runs) this is not a big deal,
but if you are like us and run several databases on one PostgreSQL instance, it would be nice to as part of the prefix include the database name.
