Hi, I took a look on this and found nice.
By the way, the parameter for REPEATABLE seems allowing to be a
expression in ParseTableSample but the grammer rejects it.
The following change seems enough.
diff --git a/src/backend/parser/gram.y b/src/backend/parser/gram.y
index 4578b5e..8cf09d5 100644
--- a/src/backend/parser/gram.y
+++ b/src/backend/parser/gram.y
@@ -10590,7 +10590,7 @@ tablesample_clause:

opt_repeatable_clause:

+ REPEATABLE '(' a_expr ')' { $$ = (Node *) $3; }

{ $$ = NULL; }
;
