Andrew Dunstan	83fcaffea2	Fix a couple of cases of JSON output. First, as noted by Itagaki Takahiro, a datum of type JSON doesn't need to be escaped. Second, ensure that numeric output not in the form of a legal JSON number is quoted and escaped.	14 years ago
Andrew Dunstan	39909d1d39	Add array_to_json and row_to_json functions. Also move the escape_json function from explain.c to json.c where it seems to belong. Andrew Dunstan, Reviewd by Abhijit Menon-Sen.	14 years ago
Robert Haas	5384a73f98	Built-in JSON data type. Like the XML data type, we simply store JSON data as text, after checking that it is valid. More complex operations such as canonicalization and comparison may come later, but this is enough for not. There are a few open issues here, such as whether we should attempt to detect UTF-8 surrogate pairs represented as \uXXXX\uYYYY, but this gets the basic framework in place.	14 years ago
