Since these names are global, using the same ones in different regression tests creates a hazard of test failures if any two such scripts run concurrently. Let's establish a policy of not doing that. In the cases where a conflict existed, I chose to rename both sides: in principle one script or the other could've been left in possession of the common name, but that seems to just invite more trouble of the same sort. There are a number of places where scripts are using names that seem unduly generic, but in the absence of actual conflicts I left them alone. In addition, fix insert.sql's use of "someone_else" as a role name. That's a flat out violation of longstanding project policy, so back-patch that change to v10 where the usage appeared. The rest of this is just future-proofing, as no two of these scripts are actually run concurrently in the existing parallel_schedule. Conflicts of schema-qualified names also exist, but will be dealt with separately. Discussion: https://postgr.es/m/4627.1521070268@sss.pgh.pa.us
