Struct ColumnMeta 

pub struct ColumnMeta {
    pub name: String,
    pub type_oid: u32,
    pub type_name: String,
}

Fields

name: String

type_oid: u32

Postgres type OID (oid 16 = bool, 23 = int4, 1184 = timestamptz, 3802 = jsonb, etc). Stable across server versions, so the UI can decide presentation (alignment, formatting) from this without a separate type-name lookup. 0 if the source statement didn’t expose a typed column descriptor (rare — only certain dynamic catalog functions).

type_name: String

Human-readable type name from pg_type.typname (int4, timestamptz, jsonb, …). Surfaces in tooltips and gives the UI a reasonable fallback label for OIDs the affinity decoder doesn’t classify.
