Re: Add contrib/pg_logicalsnapinspect

My review comments for v8-0001

======
contrib/pg_logicalinspect/pg_logicalinspect.c

+/*
+ * Lookup table for SnapBuildState.
+ */
+
+#define SNAPBUILD_STATE_INCR 1
+
+static const char *const SnapBuildStateDesc[] = {
+ [SNAPBUILD_START + SNAPBUILD_STATE_INCR] = "start",
+ [SNAPBUILD_BUILDING_SNAPSHOT + SNAPBUILD_STATE_INCR] = "building",
+ [SNAPBUILD_FULL_SNAPSHOT + SNAPBUILD_STATE_INCR] = "full",
+ [SNAPBUILD_CONSISTENT + SNAPBUILD_STATE_INCR] = "consistent",
+};
+
+/*

nit - the SNAPBUILD_STATE_INCR made this code appear more complicated
than it is. Please take a look at the attachment for an alternative
implementation which includes an explanatory comment. YMMV. Feel free
to ignore it.

src/include/replication/snapbuild.h

2.
+ * Please keep SnapBuildStateDesc[] (located in the pg_logicalinspect module)
+ * updated should a change needs to be done in SnapBuildState.

nit - "...should a change needs to be done" -- the word "needs" is
incorrect here.

How about:
"...if a change needs to be made to SnapBuildState."
"...if a change is made to SnapBuildState."
"...if SnapBuildState is changed."
