Function GetPGCodeInternal

pkg/sql/pgwire/pgerror/pgcode.go:61–77

GetPGCodeInternal retrieves a code for the error. It operates by combining the inner (cause) code and the code at the current level, at each level of cause. - at each level: - if there is a candidate code at that level, that is used; - otherwise, it calls computeDefaultCode(). if the function ret
