Just out of curiosity, it looks like I could write something like:
EXPLAIN (ANALYZE TRUE, COSTS FALSE, VERBOSE TRUE, COSTS TRUE) statement
What is the expected behavior if someone puts multiple time the same
option with different values. The last value prevails?
I know that this example looks stupid but when you have a lot of options
it sometimes happen that you put twice an option with different values
(that happens with some JDBC driver options...).
