While looking at Shigeru Hanada's foreign join pushdown patch, I noticed
a command line option that I didn't know to exist:
$ postgres --help
...
Developer options:
-f s|i|n|m|h forbid use of some plan types
That doesn't include all the options we support, the documentation
lists: s|i|o|b|t|n|m|h. These are aliases for enable_* planner options,
e.g -fs is equal to enable_seqscan=off.
That seems completely useless to me, because you can also do "-c
enable_seqscan=off". Any objections to removing the -f option altogether?
