[postgis-users] shp2pgsql loader

[Saurabh Data]

Dear users

As it says in the documentation about the shp2pgsql loader :

a)  shp2pgsql shaperoads roadstable roadsdb > roads.sql
b)  psql -d roadsdb -f roads.sql

Can someone clarify what exactly is happening in a) and b)

I understand that the a) is for conversion and b) is for uploading the file 
to psql

What I  understand is that the command shp2pgsql in a) converts a shapfile 
called "shaperoads" into roads.sql  ..but what does roadstable and roadsdb 
signify ?

Am I right in assuming that in b) , it just tries to connect to the psql 
database name roadsdb and places the file roads.sql there ?

Thanks for any help
