Store error: database unavailable on Optimism

[tkeidar]

Every query to https://api.thegraph.com/subgraphs/name/ianlapham/optimism-post-regenesis/ returns:

{
  "errors": [
    {
      "message": "Store error: database unavailable"
    }
  ]
}

it happens from time to time in the past 24 hours. I found the following article describing a possible fix to this issue: https://surfthedream.com.au/graph-indexer-store-error-database-unavailable/
