Overview

Package oidext contains oids that are not in `github.com/lib/pq/oid` as they are not shipped by default with postgres. As CRDB does not support extensions, we'll need to automatically assign a few OIDs of our own.

Constants

const (
	T_geometry   = oid.Oid(90000)
	T__geometry  = oid.Oid(90001)
	T_geography  = oid.Oid(90002)
	T__geography = oid.Oid(90003)
	T_box2d      = oid.Oid(90004)
	T__box2d     = oid.Oid(90005)
)

OIDs in this block are extensions of postgres, thus having no official OID.

const CockroachPredefinedOIDMax = 100000

CockroachPredefinedOIDMax defines the maximum OID allowed for use by non user defined types/functions. OIDs for user defined types/functions will start at CockroachPrefixedOIDMax and increase as new types are created. User defined type/function descriptors have a cluster-wide unique stable ID. CockroachPredefinedOIDMax defines the mapping from this stable ID to a type/function OID. In particular, stable ID + CockroachPredefinedOIDMax = type OID. types.StableTypeIDToOID and types.UserDefinedTypeOIDToID should be used when converting between stable ID's and type/function OIDs.

Variables

var ExtensionTypeName = map[oid.Oid]string{
	T_geometry:   "GEOMETRY",
	T__geometry:  "_GEOMETRY",
	T_geography:  "GEOGRAPHY",
	T__geography: "_GEOGRAPHY",
	T_box2d:      "BOX2D",
	T__box2d:     "_BOX2D",
}

ExtensionTypeName returns a mapping from extension oids to their type name.

Functions

func TypeName

func TypeName(o oid.Oid) (string, bool)

TypeName checks the name for a given type by first looking up oid.TypeName before falling back to looking at the oid extension ExtensionTypeName.
