Обсуждение: About a recently-added message
A recent commit added the following message: > "wal_level" must be >= logical. The use of the term "logical" here is a bit confusing, as it's unclear whether it's meant to be a natural language word or a token. (I believe it to be a token.) On the contrary, we already have the following message: > wal_level must be set to "replica" or "logical" at server start. This has the conflicting policy about quotation of variable names and enum values. I suggest making the quoting policy consistent. regards. -- Kyotaro Horiguchi NTT Open Source Software Center

Agreed, I think we have two choices here one is to use dbname without
any quotes ("dbname must be specified in \"%s\".", ...)) or use double
quotes ("\"%s\" must be specified in \"%s\".", "dbname" ...)). I see
messages like: "host name must be specified", so if we want to follow
that earlier makes more sense. Any suggestions?

Otherwise, quotes must be added. Do include quotes in a message where an arbitrary variable name is to be expanded.), I think in this case GUC's name shouldn't have been quoted. I think the patch did this because it's developed parallel to a thread where we were discussing whether to quote GUC names or not [2]. I think it is better not to do as per docs till we get any further clarification. Now, I am less clear about whether to quote "logical" or not in the above message. Do you have any suggestions?

The possible confusion comes from the fact that the sentence contains "must be"
in the middle of a comparison expression. For pg_createsubscriber, we are using
publisher requires wal_level >= logical
I suggest to use something like
slot synchronization requires wal_level >= logical

It also removes double quotes around the variable names Thanks for the discussion. With a translator hat on, I would be happy if I could determine whether a word requires translation with minimal background information. In this case, a translator needs to know which values wal_level can take. It's relatively easy in this case, but I'm not sure if this is always the case. Therefore, I would be slightly happier if "logical" were double-quoted. regards. -- Kyotaro Horiguchi NTT Open Source Software Center

Okay, now since we will have double quotes for logical. So do you
prefer the existing way of giving error msg or the changed one.
Existing:
errmsg("bad configuration for slot synchronization"),
errhint("wal_level must be >= logical."));
errmsg("bad configuration for slot synchronization"),
errhint("%s must be defined.", "primary_conninfo"));
The changed one:
errmsg("slot synchronization requires wal_level >= logical"));
errmsg("slot synchronization requires %s to be defined",
"primary_conninfo"));
thanks

I would prefer the changed ones as those clearly explain the problem
without additional information.

Yes, I'm happy with all of the changes. The proposed patch appears to cover all instances related to slotsync.c, and it looks fine to me. Thanks! I found that logica.c is also using the policy that I complained about, but it is a separate issue. ./logical.c

The patch needed to change only one test item even though it changed nine messages. This means eigh out of nine messages that the patch changed are not covered by our test. I doubt all of them are worth additional test items; however, I think we want to increase coverage. Do you think some additional tests for the rest of the messages are worth the trouble? regards. -- Kyotaro Horiguchi NTT Open Source Software Center

Hmm. I have a currently stalled patch-set to simplify the quoting of
all the GUC names by using one rule. The consensus is to *always*
quote them. See [1]. And those patches already are addressing that
logical.c code mentioned above.
IMO it would be good if we could try to get that patch set approved to
fix everything in one go, instead of ad-hoc hunting for and fixing
cases one at a time.
