There is a bug in exim 4.90 postgresql, fix:

Do you have a testcase, or description of the effect?

Compare with 4.89.1 and/or just consider the code.
    for (tuple : query) result = tuple;
was and should be:
    for (tuple : query) result += tuple;
"result" should "string_catn" to self not null.


Any multi-line query with one per line only uses the last line, the first use in my exim.conf:

domainlist local_domains = @:localhost${lookup pgsql{SELECT ':' || name FROM domain WHERE active = true}}

effect depends on use, in my case it was fatal to emails. I rank this as a major bug. If you do not use exim with postgresql you are unaffected.
