Now that we can run the regress tests using the new psql,
I was dismayed to discover that the arrays regress test
fails with it. The perfectly valid query
SELECT arrtest.a[1:3],
arrtest.b[1:1][1:2][1:2],
arrtest.c[1:2],
arrtest.d[1:1][1:2]
FROM arrtest;
fails with
ERROR: parser: parse error at or near "]"
Turning on postmaster -d reveals that what is arriving at
the backend is
SELECT arrtest.a[1],
arrtest.b[1][1][1],
arrtest.c[1],
arrtest.d[1][1]]
FROM arrtest
Needless to say, this transformation of the query
is several miles to the south of acceptable.
Over to you, Peter...
