| 06:42 <za1b1tsu> So I have a var: ['a','b']. How can I get the last element? | |
| 06:54 <flowerysong> za1b1tsu: {{ var | last }} | |
| 06:55 <flowerysong> Or {{ var[-1] }} | |
| 07:19 <za1b1tsu> but what is this syntax called {{ var | last }} etc. It is not yaml, right? | |
| 07:19 <@jborean93> it's jinja2 | |

| 09:01 <za1b1tsu> Is it possible to have a shared database on a common partition between 2 OSes? Because I'm trying to achieve this and I can't start the postgres service after changing the data_directory to the shared one. | |
| 09:01 <za1b1tsu> It's version 9.6.10 | |
| 09:02 <RhodiumToad> 2 OSes that you are dual-booting? i.e. only one is running at a time? | |
| 09:02 --> held (~heldchen@unaffiliated/held) has joined #postgresql | |
| 09:02 <RhodiumToad> the answer is that it depends on the OSes | |
| 09:03 <peerce> if their libc implementations different significantly, it may not work. | |
| 09:03 <za1b1tsu> yes dual booting, one is Mac on is Linux, but right now I'm testing this on the VM. Sice I don't want to setup everything and then realize it doesnt work and have to start other. | |
| 09:04 <peerce> what error do you get when you try and start the 'other' OS that didn't create this ? | |
| 09:04 <za1b1tsu> the problem is the postgresql log in /var/log/... does not say much or I don't know how to interpret | |
| 09:04 <RhodiumToad> mac vs linux likely wo |
