Overview ¶
Package fingerprint computes stable, semantic SQL fingerprints via libpg_query. The fingerprint is identical across comment/whitespace differences and literal-vs-placeholder differences. libpg_query is cgo-only; the !cgo build is provided by fingerprint_nocgo.go, reports Supported() == false, and returns ErrEmpty from every Fingerprint call.
This file holds the declarations shared by both builds so the two build-tagged implementations cannot drift apart.
