  "message": "Fix infinite loops in replaceStringInfoString\n\nThe function had a few problems:\n- replace \u003d\"a\" and replacement\u003d\"ab\" would give an infinite loop leading\n  to OOM. We have a similar case in pg_dump: replace\u003d\"range\",\n  replacement\u003d\"multirange\"\n- Copying the whole string each time there is a match\n- Empty replace pattern also leads to infinite loop\n\nWe can still do better: for example count number of matches and do a\nsingle allocation, or even run the replacement inplace. But it\u0027s\nprobably not worth it.\n",
