I use a PostgreSQL database on my local computer. I always import csv files via right-click to the relevant table and choosing the Import/Export Dialog. However, when I opened the pgadmin last time, there was no import/export option in the options. I do not know what happened to it. I, once, took a backup of files and use this backup file to migrate the database to another version of Postgres. I am not sure but I want to ask might one of the options that I selected or did not select cause this trouble?
I also tried to go in an alternative way by using copy from 'C://path/data.csv
method and it did not work. then I tried \copy from 'C://path/data.csv
but it did not even recognize the \ symbol and gave an error.
I wonder what happened to Postgres or pgadmin and how can I find a solution to import my data to the Postgres database?
I had the same issue, looked everywhere but nothing came up on WHY this happened or HOW to fix it.
RESOLUTION: I was able to resolve this by downloading the latest version of pgadmin4.
After downloading, the Import/Export dialog reappeared.
Hope this helps you too!
