virtual bool is_equal(const std::pmr::memory_resource& other) const noexcept = 0;
(since C++17)

Compares *this for equality with other.

Two memory_resources compare equal if and only if memory allocated from one memory_resource can be deallocated from the other and vice versa.

[edit] Notes

The most-derived type of other may not match the most derived type of *this. A derived class implementation therefore must typically check whether the most derived types of *this and other match using dynamic_cast, and immediately return false if the cast fails.
