Perl as you can select all the values in one query, or the fastest would be to create a stored procedure and call it with unlang, but i'm not that familiar with PgSQL procedures so I can't tell you how to do that.

Yes. Unlang/XLAT queries will only assign the value of the first column.

update request {
Tmp-String-0 = "%{sql:SELECT `a`, `b` FROM `foo` WHERE `bar` = 1;}"
}
Tmp-String-0 will only hold the value of column a.
