Summary

xmltext is a PostgreSQL built-in function in the String Functions group. PostgreSQL’s system catalog (pg_proc) describes it as: “generate XML text node”.

Argument and return types are taken from the pg_proc catalog; internal type names are shown using their readable SQL spellings (for example int4 is shown as integer). (Derived from the catalog — see the linked reference for the canonical documentation.)

Classification

  • Category: String Functions
  • Kind: Function
  • Volatility: IMMUTABLE — Marked IMMUTABLE — it always returns the same result for the same arguments and can be used in indexes and other contexts that require immutability.
  • Returns: xml

Example

Illustrative form (replace placeholder values with your own data):
