Explanation

Why pgcast works as it does: the ideas behind it, where its types come from, its versions and its security model. For reading away from the keyboard.

• Why pgcast

  Why pgcast works as it does: the idea it keeps from Zapatos, what the fork adds to it, and what it will never do.

• The catalog

  Every type pgcast gives you is read from your database; none is written by hand.

• Versions6.7

  Why pgcast's version numbers carry on from Zapatos's, how it decides whether a fix may change what your code gets back, and what a PGCAST_DEP00n warning is asking of you.

• Security

  What keeps a caller's input from changing the SQL pgcast sends, what it can't guard against, and how to report a flaw.
