Run a PostgreSQL sql file using command line arguments

Question

I have some  sql files with thousands of INSERT statements in them and need to run these inserts on my PostgreSQL database in order to add them to a table  The files are that large that it is impossible to open them and copy the INSERT statements into an editor window and run them there  I found on the Internet that you can use the following by navigating to the bin folder of your PostgreSQL install   psql -d myDataBase -a -f myInsertFile   In my case   psql -d HIGHWAYS -a -f CLUSTER 1000M sql   I am then asked for a password for my user  but I cannot enter anything and when I hit enter I get this error      psql  FATAL  password authentication failed for user  myUsername    Why won t it let me enter a password  Is there a way round this as it is critical that I can run these scripts   I got around this issue by adding a new entry in my pg hba conf file with the following structure     IPv6 local connections  host    myDbName    myUserName   1 128    trust   The pg hba conf file can usually be found in the  data  folder of your PostgreSQL install

Of course  you will get a fatal error for authenticating  because you do not include a user name     Try this one  it is OK for me     psql -U username -d myDataBase -a -f myInsertFile   If the database is remote  use the same command with host  psql -h host -U username -d myDataBase -a -f myInsertFile

you could even do it in this way     sudo -u postgres psql -d myDataBase -a -f myInsertFile   If you have sudo access on machine and it s not recommended for production scripts just for test on your own machine it s the easiest way

You have four choices to supply a password    Set the PGPASSWORD environment variable  For details see the manual  http   www postgresql org docs current static libpq-envars html Use a  pgpass file to store the password  For details see the manual  http   www postgresql org docs current static libpq-pgpass html Use  trust authentication  for that specific user  http   www postgresql org docs current static auth-methods html AUTH-TRUST Since PostgreSQL 9 1 you can also use a connection string  https   www postgresql org docs current static libpq-connect html LIBPQ-CONNSTRING
