This was failing for queries which try to get the .type() of a jpiLikeRegex. For example: select jsonb_path_query('["string", "string"]', '($[0] like_regex ".{7}").type()'); Reported-by: Alexander Kozhemyakin Bug: #18035 Discussion: https://postgr.es/m/18035-64af5cdcb5adf2a9@postgresql.org Backpatch-through: 12, where SQL/JSON path was added.
