Message-ID: <18224-59c34f71e2c6a5ed@postgresql.org> (raw)
The following bug has been logged on the website:
Bug reference: 18224
Logged by: Tomonari Katsumata

PostgreSQL version: 16.1
Operating system: any
Description:
Hello
I found a small bug in the error message of libpqwalreceiver.c.
According to the manual, identify_system returns one row and
four columns. (This is also the actual behavior)
https://www.postgresql.org/docs/current/protocol-replication.html#PROTOCOL-REPLICATION-IDENTIFY-SYST...
However, when data other than one row and four columns is returned,
incorrect values are reported as expected values as shown below.
＞Could not identify system: got X rows and Y fields, expected 3 rows and 1
or more fields.
It looks like the arguments are in the wrong order.
Also, it seems that the decision to return 4 fields in 9.4 was not
reflected.
This is a trivial issue, but I was curious about it so I reported it.
Best regards,
----
