Please update the guide in Docker section

[thiennq]

Hello,

When I tried using pgsync with docker

docker pull ankane/pgsync
alias pgsync="docker run -ti ankane/pgsync";
pgsync --init

No file was created.
So I think the guide in docker section should be change

From:

docker pull ankane/pgsync
alias pgsync="docker run -ti ankane/pgsync"

To:

docker pull ankane/pgsync
alias pgsync="docker run -ti -v $(pwd):/opt -w='/opt' ankane/pgsync"

Just ran into this today, thanks for posting that!

#202 -- PR here that updates the README with this info.

Thanks for the great tool.

It seems like this is run on-demand. Would it possible to implement a watcher with this so that it can run and sync in the background? not sure how difficult that is with postgres.
