but given that your regexp patterns are not anchored, they are not
equivalent. I think mine is "more correct".

Sure. First, it works fine with TCSH :). I repro a (different) failure
in BASH. But the below works fine for me:

psql "service=acme" -Xc 'select datname from pg_database where datname
!~ $$(template|postgres)$$ order by 1'

i.e. use single-quotes, and an inner $$ literal. One of 3 options an
