Overview ¶
Package pgerr classifies the Postgres error codes the SDK's own infrastructure DDL has to interpret rather than propagate. It exists because both internal/core (the dev dependency directory) and internal/contributions (the per-app contribution store) create tables lazily and must read the same two verdicts out of a driver error the same way.

Functions ¶
func RelationAlreadyExists ¶
RelationAlreadyExists reports whether err is Postgres telling us the relation we tried to create is already there. 42P07 is the direct duplicate_table verdict; 23505 is the same race observed one layer down, as a unique violation on the pg_class/pg_type catalog index, and is what CREATE TABLE IF NOT EXISTS actually raises when two backends interleave between the existence check and the insert.
Both outcomes mean THE RELATION EXISTS, which is the whole postcondition a create-if-absent helper owes its caller, so callers treat both as success.
func UndefinedTable ¶
UndefinedTable reports whether err is Postgres 42P01 — the statement named a relation that does not exist. For a table the SDK provisions per app, this is the one error that means "never provisioned for this app" rather than "the query is wrong", so a caller can create the table and retry instead of failing a request it has no other way to satisfy.
