Hi,
I would appreciate help with the syntax for querying an array of strings declared as a psql variable. Here's an example.

\set important_days ARRAY['monday', 'friday']

Not sure why the single quotes are getting stripped out but that is the issue.  Maybe double them up to escape them like in a normal text literal?

Otherwise consider just doing a comma delimited string and using string_to_array in the sql to turn it into an array at runtime.
 


\set important_days ARRAY['monday',
                          'friday']

Not with \set.  You could write sql to output the text and then execute it using \gexec to store the column value in a variable.  That too may be a solution to the missing single quotes.
