The doc (“Builds a JSON object out of a text array.”) is simply too terse to inform an answer to this question.
It does presume knowledge but it precisely defines the outcome:
PostgreSQL arrays are typed and all members are of the same type. A text array’s members are all text.
Given the above knowledge the fact that the resultant json object contains exclusively text keys and text values directly follows.
