"insert into select" support (todo: array-mode iteration error)

This is code express-session appears to use. Support for this would certainly be nice 👍 although it seems a bit complicated. I’m not sure what the point of an inner SELECT query is here since it is not actually looking up values from elsewhere but just providing them directly, but somebody better versed in SQL might know why this is clever.

Error: todo: array-mode iteration

*️⃣ Failed SQL statement: INSERT INTO "express_server_sessions" (sess, expire, sid) SELECT '{"cookie":{"originalMaxAge":1296000000,"expires":"2021-01-29T15:49:27.925Z","secure":true,"httpOnly":true,"path":"/"},"passport":{"user":653646}}', to_timestamp(1611935368), 'jCUSxo0EnzcIeCQYUgt6g3FQCoIO6Q3S' ON CONFLICT (sid) DO UPDATE SET sess='{"cookie":{"originalMaxAge":1296000000,"expires":"2021-01-29T15:49:27.925Z","secure":true,"httpOnly":true,"path":"/"},"passport":{"user":653646}}', expire=to_timestamp(1611935368) RETURNING sid;

PS: to run this code in the first place I had to work around the lack of to_timestamp:

const pgMem = require('pg-mem');
const mockDb = pgMem.newDb();


mockDb.public.registerFunction({
  name: 'to_timestamp',
  args: [pgMem.DataType.integer],
  returns: pgMem.DataType.timestampz,
  implementation: input => {
    return new Date(input * 1000).toISOString();
  },
});

I couldnt find any time to work on that this week, but it’s almost done. I’ll keep you posted, hopefully next week.

Yup… insert into select is not implemented (thanks, procrastination)… I’ll do that soon.

Thanks for the report
