Yes, one row tables :-)

What I usually do for those random values is a table like "GlobalParameters"
or similar (with three text rows: key, value, type) so I can avoid having 20
separate one row, one column tables for various settings. Defining a
trigger to coerce the value to the desired type is trivial, so your
application can depend on not having completely bogus values in these
settings.

A more esoteric possibility would be to define functions that return a
constant value.

Not exactly sure what you mean here. If you use pg_dump, usually the whole
db is dumped (table definition, data, sequences, functions, ...)
