SQL Complete seems not to be able to keep function parameters "together" on the same line. For example, if a function is broken across several lines like this:

SELECT
SUM (c1,
c2)
FROM t;

SQL Complete will not reformat to something like:

SELECT
SUM (c1, c2)
FROM t;

In general, function parameters seem not to be understood by SQL Complete. For example, it always considers AS as its own independent entity, despite it sometimes being in a function call such as:

SELECT
CAST (c1
AS INTEGER)
FROM t;

gets incorrectly formatted as:

SELECT
CAST (c1 AS
INTEGER)
FROM t;

instead of:

SELECT
CAST (c1 AS INTEGER)
FROM t;
