Sergey Nuyanzin updated CALCITE-7567:
-------------------------------------
Description:
The issue is that if there is {{TIMESTAMP}} and {{TIMESTAMP_LTZ}} with different precision
for instance {{TIMESTAMP(3)}} and {{TIMESTAMP_LTZ(0)}}
{{leastRestrictive}} from {{TIMESTAMP(3)}} and {{TIMESTAMP_LTZ(0)}}
and {{leastRestrictive}} from {{TIMESTAMP_LTZ(0)}} and {{TIMESTAMP(3)}}
return different results.
In the latest one there will be {{leastRestrictive}} with precision 0
