From 11.5 in the docs:
<bigger><bigger>"The syntax of the
</bigger></bigger><fontfamily><param>Courier</param><x-tad-bigger>CREATE
INDEX</x-tad-bigger></fontfamily><bigger><bigger> command normally
requires writing parentheses around index expressions, as shown in the
second example. The parentheses may be omitted when the expression is
just a function call, as in the first example."
</bigger></bigger>But when I try this:
db=# CREATE INDEX expression_idx on some_table( extract( year from
some_column ) );
I get a syntax error corresponding to the open parenthesis after
extract (and whitespace is not the issue).
If I add an enclosing set of parentheses, E.g.:
db=# CREATE INDEX expression_idx on some_table( ( extract( year from
some_column ) ) );
it works!
Is this a known issue?
