TextEncoder/TextDecoder polyfills for utf-8
// TextEncoder/TextDecoder polyfills for utf-8 - an implementation of TextEncoder/TextDecoder APIs

// Some important notes about the polyfill below:
// Native TextEncoder/TextDecoder implementation is overwritten
// String.prototype.codePointAt polyfill not included, as well as String.fromCodePoint
// TextEncoder.prototype.encode returns a regular array instead of Uint8Array
// No options (fatal of the TextDecoder constructor and stream of the TextDecoder.prototype.decode method) are supported.

PostgreSQL command line cheatsheet

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

  • -E: will describe the underlaying queries of the \ commands (cool for learning!)
  • -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
