One alternate and easier approach I've thought of is to simply add
something akin to a \factory-reset meta-command which would return all
settings to the state they would be in immediately after starting psql
with the --no-psqlrc option. This would at least provide one solution to the problem and might be a handy meta-command even if absolute settings
were added.

If a "factory reset" meta-command were added I think that \o should be
exempted as it is already an absolute setting that can be predictably
used in scripts and, where output redirection isn't specified in the
script, we shouldn't interfere with the ability to save the output of a
script or scripts as the user desires.

I remember some discussion about a connection-level reset, but I don't think it would apply to psql.

Another way to deal with this would be to add a command that allows you to definitively set any setting, ie:

\set timing = on

I can see value in both options.

BTW, it probably wouldn't be terribly difficult to figure out how to do the \set option. You'd have to see how commands 'plug in' to the interface (just look at any other command as an example, preferably one that takes an option), and see how options are actually set (ie: look at \timing). Coming up with a partial patch and asking for help is likely to get this done a lot sooner than just sticking it on the TODO.

options (timing, expanded, etc.) rather than toggle them.

The --no-psqlrc option provides a partial workaround - as long as
the user remembers to include it and as long as they are only
running the one script. But if they forget or if they are already
running a session there is no telling what settings have been
toggled by previously run scripts or the users themselves.

So...have I overlooked an interactive psql option that will let me
reset all options to "factory-defaults" or a method of specifying an
absolute setting to the various options?

Probably not.

If not, do psql users out there feel this is worth a feature request?

I think so.
