Not really. I think the errmsg combined with ternary is not so common.
I couldn't find many examples, so I wouldn't try to claim anything is
a "preferred" way
There are some existing examples, like Bharath had:
ereport(NOTICE,
(errcode(ERRCODE_DUPLICATE_OBJECT),
collencoding == -1
? errmsg("collation \"%s\" already exists, skipping",
collname)
: errmsg("collation \"%s\" for encoding \"%s\" already
exists, skipping",
collname, pg_encoding_to_char(collencoding))));
OTOH, when there are different numbers of substitution parameters in
each of the errmsg like that, you don't have much choice but to do it
that way.
I am fine with whatever is chosen -- I was only offering an alternative.
