Conflict target specification for PostgreSQL ON CONFLICT clause

Variants

Columns(SQL<'a, PostgresValue<'a>>)

Target specific columns: ON CONFLICT (column1, column2, …)

ColumnsWhere

Target specific columns with WHERE clause for partial unique indexes ON CONFLICT (column1, column2, …) WHERE condition

Fields

columns: SQL<'a, PostgresValue<'a>>

where_clause: SQL<'a, PostgresValue<'a>>

Constraint(String)

Target a specific constraint by name: ON CONFLICT ON CONSTRAINT constraint_name
