jsonb_set_lax

January 20, 2020/0 Comments/in Andrew's PlanetPostgreSQL /by Andrew Dunstan

Recently there were some complaints about the behaviour of the jsonb_set function. Specifically, the complain was that if the value argument of the function is null the result is null. This happens because the function is declared STRICT, like many PostgreSQL functions. STRICT is in fact another way of spelling RETURNS NULL ON NULL INPUT. […]

It is useful to perform a number of tests to verify its actual performance.

The introduction of the JSONB data type in PostgreSQL, definitely makes the “NoSQL” side of this relational DBMS come out: this introduction meets the requirements of all those who prefer a data structure in a “key-value” array, dictionary style (widely used in the field of development) and, at the same time, ensures all the advantages […]
