**First**, check to see if the package version exists for the current distro version:
--------
```
apt list -a postgresql-11-repack
```

the type of output will look something like this:
```
postgresql-11-repack/buster-pgdg 1.4.4-2.pgdg110+1 amd64 [upgradable from: 1.4.4-1.pgdg110+1]
postgresql-11-repack/now 1.4.4-1.pgdg110+1 amd64 [installed,upgradable to: 1.4.4-2.pgdg110+1]
```


<br/>

**If the package version you need is listed, you can then remove the existing package and install the specific version needed by doing:**
```
sudo apt-get --purge remove postgresql-11-repack

sudo apt-get install postgresql-11-repack=1.4.4-2
```

<br/>

**If the package does not show up, you can alternatively build it from source:**

```
git clone https://github.com/reorg/pg_repack.git
cd pg_repack/
git checkout tags/ver_1.4.4
make
make install
```

*One reason you might want to build from source is because the version of the package you need is from a previous version of the OS and you do not want to deal with that type of joy specifically ([example][1])*
