QUESTION
After having everything working on my Heroku app for months, I started getting this error yesterday:
no pg_hba.conf entry for host "x.x.x.x", user "xxxxx", database "xxxxz", SSL off"
I've only been working on the client side and haven't changed anything on the server, so I don't know what could be going on.
server package.json

QUESTION
I keep running into this error
...ANSWER
Answered 2020-Sep-03 at 01:18The error is telling you that the migration script 001.do.create_folders_table.sql
has changed since it was first created. To fix the error you need to ensure that the contents of the file are exactly the same as when they were when the script first ran. Can you use git to check out an old version of the file?
The checksum is a string of characters called a hash. It is created by using the script as input to an algorithm called md5. Depending on your machine, you might have a command line version of md5 can try for yourself. Try md5 001.do.create_folders_table.sql
and you will see the output. Probably something like: ce662acdd491b642c6db551983f878cd
.
Postgrator stores these md5 hashes. To ensure that the database is put into the same state every time the migrations are run, it will put the script through md5 and compare the result with the stored version. If the current version and the sotred version are different, then the script must have changed which means it is not safe to run the migration.
QUESTION
I feel like the foot traffic is slow on Unix&Linux, so I'm also posting this question here:
I have a Postgres installed in CentOS, along with Node and React with NGINX. I've left alone my Unix postgres
account to be without a password as recommended here. I've also written migrations with postgrator, which creates a table as blog_user
in the blog_database
.
My blog_user
has LOGIN
attribute with encrypted password, and the database blog_database
is owned by postgres
.
When I run my migrations in CentOS, I get this message
