[GRASSLIST:7182] r.to.pg

[Firman Hadi]

Dear all,

I want to export raster to postgres by using r.to.pg but the result is 
an error message like this:

cat: /home/firman/.grassrc5: No such file or directory
Please select database with g.select.pg or db.connect

I have tried to use g.select.pg but it wasn't change anything.
What I get from this error message is GRASS tried to read .grassrc5, but 
GRASS 5.4 that I used is
reading .grassrc54.
Is there anybody can help?
Thanks,
