Seems 'not at the moment'.
Background:
We use the SQL : 'SELECT <SQL DB attribute> AS <dovecot variable>'
..elsewhere.
Tests (so far) have show this SQL 'AS' assignment does NOT work in Exim ACL's -
whether quoted, bracketed, or $quote_pgsl:'ed, and whether destined for either
an acl_<variable> OR a MACRO.
Not definitve - more clever minds may yet find a way....
NB: We have never bothered, as PostgreSQL can handle multiple calls 'fast
enough' and with better-known (to us) predictability, than we might expect with
interpreted-language string surgery on sometimes-but-not-always UTF-8.
'Always' 7-level ASCII would perhaps be a whole different game, so...
