Synopsis

searchFunctions(web_search)

Description

Search functions and procedures by name, source, language, trigger name, or description.

Parameters

web_search requiredstring

Also accepts connection, instance, group, described once under arguments every tool takes.

Output

Keyed by schema-qualified function signature; each value is that routine's signature and properties. An absent extension or a missing grant is reported as {error, hint} in place of the map.

Scope

A physical replica is byte-identical here, so asking each member of a replication group adds nothing.
