|
|    Add 'unit' parameter to ExplainProperty{Integer,Float}.
|    
|    This allows to deduplicate some existing code, but mainly avoids some
|    duplication in upcoming commits.
|    
|    In passing, fix variable names indicating wrong unit (seconds instead
|    of ms).

There's 3 pairs of these, and the other two pairs use "ms":

$ git grep 'Actual.*Time' src/backend/commands/explain.c 
src/backend/commands/explain.c:                         ExplainPropertyFloat("Actual Startup Time", "s", startup_ms,
src/backend/commands/explain.c:                         ExplainPropertyFloat("Actual Total Time", "s", total_ms,
src/backend/commands/explain.c:                         ExplainPropertyFloat("Actual Startup Time", "ms", 0.0, 3, es);
src/backend/commands/explain.c:                         ExplainPropertyFloat("Actual Total Time", "ms", 0.0, 3, es);
src/backend/commands/explain.c:                                 ExplainPropertyFloat("Actual Startup Time", "ms",
src/backend/commands/explain.c:                                 ExplainPropertyFloat("Actual Total Time", "ms",

Text mode uses appendStringInfo() for high density output, so this only affects
non-text output, but it turns out that units aren't shown for nontext format
anyway - this seems like a deficiency, but it means there's no visible bug.
