Postgres Pg_Dump failed due to non english character on database name - postgresql

I have created a postgres data base by giving non ascii name example: "Química"
When I tried to take back up of the same database using following command I am getting the exception
pg_dump: [archiver (db)] connection to database "Química" failed: FATAL: database "Química" does not exist.
Command used:
--host 127.0.0.1 --port 7555 --username postgres --format=d --verbose --jobs=10 --compress 9 --file "C:\Delete\Archive" --dbname "Química" --schema "Archive_TVT"

Lost all tables when upgrading PostgreSQL from v11 12

I upgraded Postgres and now it doesn't show any tables. Can anyone help?
This is the error:
Error: Upgrading postgresql data from 11 to 12 failed!

PostgreSQL's pg_restore error while restoring

I took a backup of database from remote server using pg_dump from my local in directory format. The version of postgres remote server's is 9.3.23 and my postgres local version is 9.6. So, when i am trying to restore, the data gets restored but it's throwing few errors.
This is the command I used for dumping:
pg_dump -h 172.16.0.70 -U postgres -d enet -n finance -Fd -j5 -f fin
This is the command i used for restoring:
pg_restore -h 172.16.0.70 -U postgres -d newdb08aug19 -j5 fin
-- Dumped from database version 9.3.23
-- Dumped by pg_dump version 9.6.14

Command was: SET idle_in_transaction_session_timeout = 0;

MongoImport error: Failed: error connecting to db server: no reachable servers, openssl error: Host validation error

When I'm trying to import json to my MongoDB which is password authenticated, encrypted and TLS/SSL based connection, I'm getting error.
This is the mongoImport Im writting:
mongoimport --verbose --ssl --sslCAFile "C:\server\cert\rootCA.pem" --sslPEMKeyFile "C:\server\cert\server.pem" --sslFIPSMode --host 127.0.0.1 --port 27017 --username databaseAdmin --password password123 --authenticationDatabase admin --db test_coll --collection blocks --file "C:\data\blocks.json"
And I got the following error message:
2018-07-20T15:21:27.365+0530 filesize: 6392 bytes
2018-07-20T15:21:27.366+0530 using fields:

2018-07-20T15:21:30.928+0530 imported 0 documents
Hostname in their certificates should match the specified hostname. So, I updated my hostname to localhost.
Now, my mongoimport command looks like:
mongoimport --verbose --ssl --sslCAFile "C:\server\cert\rootCA.pem" --sslPEMKeyFile "C:\server\cert\server.pem" --sslFIPSMode --host localhost --port 27017 --username databaseAdmin --password password123 --authenticationDatabase admin --db test_coll --collection blocks --file "C:\data\blocks.json"
And now it works.

postgresql: errors install and run postgresql-9.5

I installed two postgresql(s), 9.5 should use port 5433, 9.3.4 should use port 5432:
me#camb:/usr/lib/postgresql/9.5/bin$ ls -al psql
-rwxr-xr-x 1 root root 564464 Jan 7 14:54 psql

postgres:x:200:
me#camb:/opt/pkgs/postgresql-9.3.4/bin$ groups postgres

I wrote a script to install postgresql-9.5 and migrate from 9.3.4 to 9.5
Problem 0: postgresql-9.5 can not start sucessfully and why status is online
Output during install:

Thanks
By the way, I run the following to do migration:
sudo -u postgres /opt/pkgs/postgresql-9.3.4/bin/pg_dumpall -p 5432 | sudo -u postgres /opt/pkgs/postgresql-9.3.4/bin/psql -p 5433
Thanks
You have to use the same libpq library as the one used in psql 9.5.
You should do the following:
export LD_LIBRARY_PATH=/usr/lib/postgresql/9.5/lib:$LD_LIBRARY_PATH
sudo /sbin/ldconfig /usr/lib/postgresql/9.5/lib
You mess up with different versions of postgresql.
To start/use 9.5, you must use the appropriate binaries: initdb, pg_ctl and psql (for example):
mkdir /usr/lib/postgresql/9.5/data
/usr/lib/postgresql/9.5/bin/initdb -D ../data/
/usr/lib/postgresql/9.5/bin/pg_ctl -D ../data/ -l logfile start
/usr/lib/postgresql/9.5/bin/psql -p 5432 -d template1
More info: https://www.postgresql.org/docs/devel/static/install-post.html
and PQsslInUse issue: http://postgresql.nabble.com/psql-error-on-postgresql-9-0-psql-symbol-lookup-error-psql-undefined-symbol-PQconnectdbParams-td5104930.html
The error is "undefined symbol: PQsslInUse"
I just ran into this problem myself. I discovered that the reason was because I compiled Postgres 9.5 from scratch into a particular directory and then decided that I wanted it elsewhere and moved the install to a new directory. Down the line when I went to restore my database with psql, I got the above error. I corrected the problem by deleting my installation directory, changing the PREFIX to the correct location, recompiling and reinstalling Postgres. psql worked fine after this.
I had the same problem
psql: symbol lookup error: psql: undefined symbol: PQsetErrorContextVisibility
And the solution is :
export LD_LIBRARY_PATH=$PGXZ_HOME/lib:${LD_LIBRARY_PATH}
I had a similar issue and finally found a solution:
My user did not have permission for the postgres installation.
What worked for me was to switch to the postgres user:
sudo su - postgres
psql
and then it worked no issues.
