1. use mysqldump to dump database from mysql:

mysqldump --compatible=postgresql --default-character-set=utf8 --hex-blob -r databasename.mysql -u root databasename -p

Note: Option --compatible=postgresql doesn't work on mysql8.0+, so if your mysql version is greater than 8.0, you can use:

mysqldump --default-character-set=utf8 --hex-blob -r databasename.mysql -u root databasename -p

If you just wan't to dump scheme witout data, please add -d option:

mysqldump --default-character-set=utf8 --hex-blob -r databasename.mysql -u root databasename -d -p

2. convert the dump file to postgresql script:
   mysql2postgresql -i databasename.mysql -o databasename.sql
3. use the script with psql:
   \i databasename.sql
