pgsql: Great TODO updates from Tom: < Currently SIGTERM of a backend

Log Message:
-----------
Great TODO updates from Tom:

<   Currently SIGTERM of a backend can lead to lock table corruption.
>   Lock table corruption following SIGTERM of an individual backend
>   has been reported in 8.0.  A possible cause was fixed in 8.1, but
>   it is unknown whether other problems exist.  This item mostly
>   requires additional testing rather than of writing any new code.
<     o Allow postgresql.conf values to be set so they can not be changed
<       by the user

< * %Remove Money type, add money formatting for decimal type
> * Improve the MONEY data type
