Functions ¶

func CheckPermissions ¶

func CheckPermissions(fi os.FileInfo) error

func ErrNotExists ¶

func ErrNotExists(err error) bool

ErrNotExists reports if err is a "path doesn't exist" type error.

fs.ErrNotExist is not enough, as "/dev/null/somefile" will return ENOTDIR instead of ENOENT.

func Home ¶

func Home(subdir bool) string

Home gets the PostgreSQL configuration dir in the user's home directory: %APPDATA%/postgresql on Windows, and $HOME/.postgresql/postgresql.crt everywhere else.

Returns an empy string if no home directory was found.

Matches pqGetHomeDirectory() from PostgreSQL. https://github.com/postgres/postgres/blob/2b117bb/src/interfaces/libpq/fe-connect.c#L8214

func Join ¶

func Join[S ~[]E, E ~string](s S) string

func ParseBool ¶

func ParseBool(str string) (bool, error)

ParseBool is like strconv.ParseBool, but also accepts "yes"/"no" and "on"/"off".

func Pgpass ¶

func Pgpass(passfile string) string

Pgpass gets the filepath to the pgpass file to use, returning "" if a pgpass file shouldn't be used.

func SSLKeyPermissions ¶

func SSLKeyPermissions(sslkey string) error

SSLKeyPermissions checks the permissions on user-supplied SSL key files, which should have very little access. libpq does not check key file permissions on Windows.

If the file is owned by the same user the process is running as, the file should only have 0600. If the file is owned by root, and the group matches the group that the process is running in, the permissions cannot be more than 0640. The file should never have world permissions.

Returns an error when the permission check fails.

func User ¶

func User() (string, error)
