3.4) What debugging features are available?
- PostgreSQL has several features that report status information that
- can be valuable for debugging purposes.
+ There are many log_* server configuration variables that enable
+ printing of query and process statistics which can be very useful for
+ debugging and performance measurements.
- First, by running configure with the --enable-cassert option, many
- assert()s monitor the progress of the backend and halt the program

+ The following detailed debug instructions are to be used to provide

- Both postmaster and postgres have several debug options available.
- First, whenever you start postmaster, make sure you send the standard
- output and error to a log file, like:
- cd /usr/local/pgsql
- ./bin/postmaster >server.log 2>&1 &
