Symbols in Redshift User Passwords work just fine


Recently read a few posts / discussions about people doubting Redshift not accepting (working-well with) ASCII symbols in User-Passwords.

It felt like a good time to write this short post showing that Redshift (Engine) seems to work fine with (non-alphanumeric) (printable) ASCII symbols.

You can see a few things (in the sample output given below):

  • All non-alphanumeric printable ASCII characters worked fine (at least all that my US-International / QWERTY keyboard could throw at it)
  • For those who also need ' (single-quote) and " (double-quote) you could always use $$ as quote-delimiters
  • You still need at least One of each of the following:
    • Upper-Case English-Letter
    • Lower-Case English-Letter
    • One Digit / Numeral
