Hello,
the comment-begin should be useful in psql, even if the user has not
explicitly set comment-begin to be usefull (--):
Change comment-begin, if it has the libreadline default value:
diff --git a/src/bin/psql/input.c b/src/bin/psql/input.c
index 2359b11dcd..93da7f7c75 100644
--- a/src/bin/psql/input.c
+++ b/src/bin/psql/input.c
@@ -356,6 +356,8 @@ initializeInput(int flags) /* these two things must be done in this order: */
initialize_readline(); rl_initialize();
+ if (!strcmp("#", rl_variable_value("comment-begin")))
+ rl_variable_bind("comment-begin", "--");
useHistory = true; using_history();
Greetings Дилян
