Documentation

Overview

Package pgschema applies PostgreSQL-only schema objects that Ent's schema definitions cannot express, such as expression indexes. Apply it after Ent's migration, and only against PostgreSQL.

Index

Constants

View Source 
const HumanEmailIndex = "sf_humans_email_lower_key"

HumanEmailIndex is the unique index on lower(email) in sf_humans. The column's own unique constraint is case-sensitive, while every email lookup is case-insensitive, so this index is what prevents two humans whose emails differ only in case.

Functions

func Apply 

func Apply(ctx context.Context, db Execer) error

Apply creates the PostgreSQL-only schema objects. It is idempotent. It fails if existing rows violate an index, for example two humans whose emails differ only in case; resolve those rows and run it again.

Types

type Execer 

type Execer interface {
	ExecContext(ctx context.Context, query string, args ...any) (sql.Result, error)
}

Execer runs a statement. *sql.DB, *sql.Tx, and the identity Ent client all satisfy it.
