Module generated_values 

PostgreSQL rules for the values a statement writes to the columns whose values a table generates: identity columns and generated columns.

Structs

GeneratedValueColumns

The identity and generated columns of one table, in column order, read once for a statement that writes it. PostgreSQL applies these rules when it rewrites the statement, column by column in table order, before it reads or writes a row, so a statement whose source yields no row is rejected as well.
