pub fn intern(name: &str) -> Option<&'static str>Expand description
The constant naming this catalog table, for a name that arrives as a
relname string from pg_depend or pg_description.
The shared maps key on the constants rather than on owned strings, so a lookup allocates nothing. A row addressed through some other catalog table (a comment on a language, an extension owning a text-search configuration) has no constant and is not interned: nothing here looks it up.
