After installing PSQL 15.1 (https://www.postgresql.org/download/), I try to connect to the server, enter the password that I set during installation. But I am getting this error [connection to server at "localhost" (::1), port 5432 failed: FATAL: password authentication failed for user "postgres"]
enter image description here
Any idea how can I fix this? Thanks!
I use flink cdc 2.0.0 to connect to postgresql in vmware.
I can connect to mysql in VM and do the SELECT in my code. But I can't do the same to postgres. And it throw an exception 'FATAL: no pg_hba.conf entry for host "192.168.42.1", user "postgres", database "mydb", SSL off error'

I have modified the settings in pg_hba.conf and postgresql.conf:
host all all all trust # at the bottom of the file
listen_addresses = '*'
And it's weird that there's no problem using the database tool DBeaver, this can create and select...
Here's my code:
DebeziumSourceFunction<String> source = PostgreSQLSource.<String>builder()
.hostname("192.168.42.130")
.port(5432)
.username("postgres")
.password("123456")
.database("mydb")
.schemaList("public")
.tableList("big_data_public.public.user")
.deserializer(new StringDebeziumDeserializationSchema())
.build();
The ip '192.168.42.130' is the ip of my VM.
The ip '192.168.42.1' is the ip of VMware Network Adapter VMnet8.(I don't understand why the code throw an exception with this IP)
I'm using Windows 8.1 PosgreSQL 9.5 and withn I try to exeucte pg_dump and asking for the password after I enter the correct password, I'm getting this error:
What do I need to do?
pg_dump: [archiver (db)] connection to database "Nick" failed: FATAL:
password authentication failed for user "Nick"
I do not have database called "Nick" in my postgreSQL
I'm trying to connect MongoDB database on modulus.io by referencing [this][1] tutorial.
I've registered with modules .io and received the database url. (Modulus provides the database URL you need and you can use mongoose.connect to connect to it)
i.e.
MONGO URI
mongodb://<user>:<pass>#apollo.modulusmongo.net:27017/wIp4otyd
MONGO CONSOLE
mongo apollo.modulusmongo.net:27017/wIp4otyd -u <user> -p <pass>
But when I'm trying to connect it through both node.js and console its showing me following error:

I'm trying to start a play application in a console on heroku using this line of code:
new play.core.StaticApplication(new java.io.File("."))
Unfortunately it seems to be having a problem connecting to my database. I'm using postgres. Here's my configuration from application.conf
db.default.driver=org.postgresql.Driver
db.default.url=${?DATABASE_URL}
db.default.user=myusername
db.default.password=mypassword
My app is able to access the database through regular use. Here's the error i'm getting:
c.j.b.h.AbstractConnectionHook - Failed to obtain initial connection Sleeping for 0ms and trying again. Attempts left: 0. Exception: java.net.ConnectException: Connection refused.Message:Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.
