@Robie: It's been a while since I dabbled with this, but to me this is not really "wishlist", it's an actual bug. Surely pg_wrapper doesn't document that it looks at the explicitly specified port, but it certainly ought to. This case was just plain forgotten.
So the patch certainly needs some massaging, at least: - adjust it to current version [1], which e. g. has $explicit_port instead of $port_specified - Fix the "locahost" typo, and support IP addresses as well (127.0.0.* or ::1) - Add an integration test to https://salsa.debian.org/postgresql/postgresql-common/blob/master/t/090_multicluster.t but the general heading of it seems fine to me. [1] https://salsa.debian.org/postgresql/postgresql- common/blob/master/pg_wrapper ** Changed in: postgresql-common (Ubuntu) Importance: Wishlist => Medium -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to postgresql-common in Ubuntu. https://bugs.launchpad.net/bugs/1796407 Title: pg_wrapper doesn't work when -p is used Status in postgresql-common package in Ubuntu: Triaged Bug description: Release: 16.04 pg_wrapper currently relies upon either run-time-supplied data or fixed files which can become out of date to select the correct version of clients. Alternatively it chooses (potentially incompatible) versions of installed programs based on which cluster is using port 5432, even when a different port is in use, despite code intended to default to the newest version. The problem is that the call to user_cluster_map() returns the default port, and thus the condition just below this comment is not executed: # if we only have a port, but no version here, use the latest version # TODO: this could be improved by better argument parsing and mapping back the # port to a cluster version/name if (!$version and $port_specified) { $version = get_newest_version; } E.g. (here shown for an old system which has 9.1 on port 5432, and 9.3 on port 5433, similar results have been obtained on more up to date systems): pg_dump -p 5433 pg_dump: server version: 9.3.24; pg_dump version: 9.1.24 pg_dump: aborting because of server version mismatch Observed behaviour, ignore port value and newest version and instead choose version from port 5432. Expected behaviour: (as per code below comment) choose version 9.3 The supplied patch implements the TODO: above. If a port (and no host other than localhost) has been specified, it interrogates the configuration files to identify which cluster and version is listening on the specified port (via -p, --port or PGPORT environment variable) and selects those in the case that a port has been specified. NB. the patch will probably not apply cleanly to the current version in debian/sid, as some reworking of that has happened. Looking at that code, however, the problem addressed here has not gone away: user_cluster_map() still returns a port while the code in pg_wrapper expects it not to.
