|Hello:
|
|I have an identical query that has similar explain plan on both Prod
and Dev
|environment, only difference being that certain indexes are
performing
|unique scan on Prod and Range scan on Dev.
|Can you cast some light on how this can be matched and under what
conditions
|this discrepancy might occur.
