Hi,
This is a minor leak, oversight in
https://github.com/postgres/postgres/commit/4526951d564a7eed512b4a0ac3b5893e0a115690#diff-e399f5c029192320f310a79f18c20fb18c8e916fee993237f6f82f05dad851c5
ExplainPropertyText does not save the *relations->data* pointer and
var relations goes out of scope.
No need to backpatch.
regards,
Ranier Vilela
