Information on relevant USE flags:
 * doc: Include the online documentation to be stored on your system
 * pg_legacytimestamp: Use the older, floating-point method for formatting timestamps instead of the higher resolution 64-bit integer method. Unless you had a previous installation that utilized this deprecated method, leave this USE flag disabled. Flipping 'pg_legacytimestamp' will require you to do a dump and restore if any of your databases utilize timestamps. The two methods are incompatible with each other.
 * readline: You really want this enabled. Disabling removes command line editing and history in psql.
 * selinux: This can only be enabled by using the SELinux profile.
 * uuid: Include support to generate a 128 bit random unique identifier. This is useful for merging databases together so the chances of collisions become extremely low.
