Postgres Extension

To be able to use the ltree type, you'll have to enable the postgres ltree extension first.

See AshPostgres.Repo

Constraints

• :escape? (boolean/0) - Escape the ltree segments to make it possible to include characters that are either . (the separation character) or any other unsupported character like - (Postgres <= 15).
  If the option is enabled, any characters besides [0-9a-zA-Z] will be replaced with _[HEX Ascii Code].
  Additionally the type will no longer take strings as user input since it's impossible to decide between . being a separator or part of a segment.
  If the option is disabled, any string will be relayed directly to postgres. If the segments are provided as a list, they can't contain . since postgres would split the segment.

• :min_length (non_neg_integer/0) - A minimum length for the tree segments.

• :max_length (non_neg_integer/0) - A maximum length for the tree segments.
