It seems this is one of these things I keep forgetting how to perform |
| 2 |
correctly, despite taking notes and reading the documentation. I thought I |
| 3 |
had upgraded postgresql from 9.5.7 to 9.6.3-r1 a couple of weeks ago. |
| 4 |
|
| 5 |
Today depclean asked me to remove 9.5.7 and after a moment's hesitation I went |
| 6 |
along with it. To my surprise I got this at the end of it: |
| 7 |

Looking at /usr/include/ I see this: |
| 42 |
|
| 43 |
lrwxrwxrwx 1 root root 29 Jul 16 13:56 postgres_ext.h -> |
| 44 |
postgresql-9.5/postgres_ext.h |
| 45 |
lrwxrwxrwx 1 root root 14 Jul 29 10:34 postgresql -> postgresql-9.6 |
| 46 |
drwxr-xr-x 6 root root 4096 Jul 16 13:55 postgresql-9.6 |
| 47 |
|
| 48 |
Although the old /usr/include/postgresql-9.5 directory and file postgres_ext.h |
| 49 |
have been removed, the symlink is still pointint to the old file, rather than |
| 50 |
having been replaced with a symlink to |
| 51 |
/usr/include/postgresql-9.6/postgres_ext.h: |
| 52 |
|
| 53 |
$ ls -la /usr/include/postgresql-9.6/postgres_ext.h |
| 54 |
-rw-r--r-- 1 root root 2151 Jul 16 13:54 |
| 55 |
/usr/include/postgresql-9.6/postgres_ext.h |
| 56 |
|
| 57 |
|
| 58 |
I'm trying to understand why this might have happened. Which process/action |
| 59 |
is responsible for setting this symlink? |
| 60 |
|
| 61 |
Also, the entry run by depclean above also confused me: |
| 62 |
|
| 63 |
Unsetting 9.5 as default...done. |
| 64 |
Setting 9.6 as the default... |
| 65 |
|
| 66 |
How is the default version of postgresql being set in a system? What specific |
| 67 |
actions do these two entries entail? I thought with openrc at least it is a |
| 68 |
matter of setting up the latest postgresql version to start up in rc-update. |
| 69 |
|
| 70 |
I've replaced the symlink with the live postgresql manually for now - I hope I |
| 71 |
haven't borked the database ... |
