Fix timestamp range handling in regression tests of modules/commit_ts/
Switching the regression tests to use tstzrange() has proved to not be agood idea for environments where the timestamp precision is low, asinternal range checks exclude the upper bound. So, if the committimestamp of a transaction matched with now() from the next query,the test would fail. This changes to use two bound checks instead ofthe range function, where the upper bound is inclusive.Per buildfarm member jacana.Discussion:https://postgr.es/m/20200712122507.GD21680@paquier.xyz
