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. https://www.postgresql.org/docs/current/sql-expressions.html#SQL-EXPRESSIONS-SUBSCRIPTS 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. David J.
