对于编码不一致的错误

msf > db_connect postgres:toor@127.0.0.1:7337/msf4

[-] Error while running command db_connect: Failed to connect to the database: PGError: ERROR: new encoding (UTF8) is incompatible with the encoding of the template database (sql_ASCII)

HINT: Use the same encoding as in the template database,or use template0 as template.

: CREATE DATABASE "msf4" ENCODING = 'utf8'

切换到Postgresql安装目录/bin/下

createdb mydb -E UTF8 -T template0

mydb为你想创建的数据库名称

然后在MSF里执行:db_connect postgresql:toor@127.0.0.1:7337/mydb 就OK了
