Below is my shell script, I am trying to insert columns in posrgresql using shell script.
But getting below error.

psql "host=$HOST port=$DBPORT dbname=$DBNAME user=$DBUSER password=$DBPASS" -F --no-align <<EOF
truncate table stg.notification_table;
\set fname $i

Please help to resolve.

There is no need to use these variables with \set.
Here is an example:
message="INFO: Load into table 'stg_ft_raw_activity' completed, 362554 record(s) loaded successfully.
INFO: Load into table 'stg_ft_raw_activity' completed, 1 record(s) were loaded with replacements made for ACCEPTINVCHARS. Check 'stl_replacements' system table for details.
"
psql <<EOF
INSERT INTO message_table VALUES (\$\$$message\$\$);
EOF
This makes use of “dollar quoting” for string literals, with the $ signs that are no shell variable reference escaped with backslashes.
