Hey,
A post over in Reddit had an expression form I've never seen before:
select (array[1,2,3,4]::integer[])[generate_series(1, 3)];
===
1
2
3
Looking at subscripting in the SQL syntax this example doesn't seem to be documented.
Is it documented somewhere else, and, regardless, shouldn't it be documented in the linked location?
I get this is basically a variant of the slice syntax [n:m], and it is working as expected, but nothing indicates I can put an SRF inside the brackets.
