type IOCacheKey ¶

type IOCacheKey struct {
	Tablespace pg.OID
	Database   pg.OID
	Relation   pg.OID
	Block      pg.HeapBlockNumber
}

IOCacheKey contains the forward lookup information for a given relation file. IOCacheKey is a [comparable](https://golang.org/ref/spec#Comparison_operators) struct suitable for use as a lookup key. These values are immutable and map 1:1 with the string inputs read from the pg_xlogdump(1) scanning utility.
