I suggest we call it "xmlformat", which is an established term for this.

Some very-very old, rusted memory told me that there was something in standard – and indeed, it seems it described an optional Feature X069, “XMLSerialize: INDENT” for XMLSERIALIZE. So probably pretty-printing should go there, to XMLSERIALIZE, to follow the standard?

Oracle also has an option for it in XMLSERIALIZE, although in a slightly different form, with ability to specify the number of spaces for indentation https://docs.oracle.com/database/121/SQLRF/functions268.htm#SQLRF06231.

Hi Nikolay,

My first thought was to call it xmlpretty, to make it consistent with the jsonb equivalent "jsonb_pretty". But yes, you make a good observation .. xmlserialize seems to be a much better candidate.

I would be willing to refactor my patch if we agree on xmlserialize.

Thanks for the suggestion!

Jim
