 ## currently, this script makes a lot of assumptions:
-## 1) location of guc.c and postgresql.conf.sample relative to script
-##       For postgresql.conf.sample
-## 2) the valid config settings may be preceded by a '#', but NOT '# '
-## 3) the valid config settings will be followed immediately by  ' =' 
-##    (at least one space preceding the '='
-##       For guc.c
-## 4) the options have PGC_ on the same line as the option
-## 5) the options have '{ ' on the same line as the option
