Re: [PATCH v1] Fix parsing of a complex type that has an array of complex types - Mailing list pgsql-hackers

I agree with all your points as I encountered them myself, especially ambiguity and error handling.

The introduced dependency between those functions also is for me a bad idea but it seemed like the only way to support that use case, but turns out my assumption that the array literal shouldn't be quoted was wrong,

I managed to execute this query fine:
INSERT INTO item_2d_table VALUES(1, '(1,"{{""(\\""inv a\\"",42,1.99)"",""(\\"inv b\\",42,1.99)""},{""(\\""inv c\\"",42,1.99)"",""(\\""inv d\\"",42,2)""}}")');

Thanks for your insights on this,

Kind regards,
Arjan Marku
