RE: expand array for in-clause, its definitely not supported automatically by node-postgres:

http://stackoverflow.com/questions/10720420/node-postgres-ho... https://github.com/brianc/node-postgres/issues/431

which I confirmed:

promise catch err: { [error: invalid input syntax for integer: "{"45","56","33"}"]

but I can make this work by altering my 'sql' tagged template string function, and inspect for typeof <var> array and automatically expand. I wonder if there are there other purposes for arrays other than the in-clause syntax that I should check for.
