Uniswap Watcher

Setup

Create a postgres12 database for the job queue:

sudo su - postgres
createdb uni-watcher-job-queue

Enable the pgcrypto extension on the job queue database (https://github.com/timgit/pg-boss/blob/master/docs/usage.md#intro).

Example:

postgres@tesla:~$ psql -U postgres -h localhost uni-watcher-job-queue
Password for user postgres:
psql (12.7 (Ubuntu 12.7-1.pgdg18.04+1))
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
Type "help" for help.

uni-watcher-job-queue=# CREATE EXTENSION pgcrypto;
CREATE EXTENSION
uni-watcher-job-queue=# exit

Create a postgres12 database for the address watcher:

Update environments/local.toml with database connection settings for both the databases.
