调研方向
Start with the reported httpuv::startServer entry point and reproduce the two DBI::dbConnect calls on Windows using PostgreSQL pgpass authentication. Compare the Windows behavior with Ubuntu 14.04 and trace what changes after startServer; done means identifying whether httpuv causes the failure and establishing a verified fix or clear diagnosis.

描述
I've already asked this question here , but since nobody answered it I've made additional tests and discover that problem lies in httpuv.
In short - I've my password for database connection stored in pgpass file as described in documentation (link). Usually works OK, but after running startServer it fails. Look on the example (I've translated error message from Polish by myself, so it may look slightly different):
con <- DBI::dbConnect(RPostgres::Postgres(), dbname = "mydb",
user = "username",
host = "localhost",
port = "5432")
# connection is established withour errors
serwer <- httpuv::startServer("127.0.0.1", 6442, list())
con <- DBI::dbConnect(RPostgres::Postgres(), dbname = "mydb",
user = "username",
host = "localhost",
port = "5432")
# Error: FATAL: password authentication failed for user "username"
password retrieved from file "C:\Users\...\AppData\Roaming/postgresql/pgpass.conf"
Read my question on stackoverflow for details.
I've tried to replicate this behaviour on Ubuntu 14.04 64-bit, but everything worked smoothly, so it must be something in windows (I've checked it also on Windows 8 and the error was exactly the same).
I am not sure if this is an issue with httpuv package but I guess it's the best place to ask.
