By following steps you can neglect the double quotes at the time of using postgres COPY restoration

1. connecting windows server

D:
cd D:\PostgresPlus\9.4AS\bin
psql -U enterprisedb -d Health_DC

2. Sample Data’s :

"city_name"|"pincode"|"taluka_name"|"district_name"|"state_name"
"Arong"|"744301"|"Car Nicobar"|"Nicobar"|"Andaman and Nicobar Islands"
"Sawai"|"744301"|"Car Nicobar"|"Nicobar"|"Andaman and Nicobar Islands"
"Chuckchucha"|"744301"|"Car Nicobar"|"Nicobar"|"Andaman and Nicobar Islands"
"Kinyuka"|"744301"|"Car Nicobar"|"Nicobar"|"Andaman and Nicobar Islands"
"Big Lapati"|"744301"|"Car Nicobar"|"Nicobar"|"Andaman and Nicobar Islands"

3. following copy command will neglect the double quote

2ndquadrant.in=# COPY ehis.citytemp FROM 'D:\InCampusDB/city_master_data.csv' DELIMITER '|' CSV HEADER;
ERROR: character with byte sequence 0x9d in encoding "WIN1252" has no equivalent in encoding "UTF8"
CONTEXT: COPY citytemp, line 358646

You need to change the character set on your windows command line before running the script with chcp. Or in postgresql you can:

SET CLIENT_ENCODING TO 'utf8';
Before importing the file.

2ndquadrant.in=# SET CLIENT_ENCODING TO 'utf8';
SET
2ndquadrant.in=# COPY ehis.citytemp FROM 'D:\InCampusDB/city_master_data.csv' DELIMITER '|' CSV HEADER;
COPY 679249

You might have noticed that after bulk inserting records using the COPY statement in PostgreSQL the sequence IDs are not getting updated for any further inserts later on, and it would throw duplicate sequence ID errors.
So you would be wondering what makes this COPY statement different that it does not update the sequences,Don’t forget to update the sequence in PostgreSQL after a COPY command.

Use Below anyone of command to update the postgres sequence after bulk insertion or after COPY TO command.

ALTER SEQUENCE ehis.citymaster_seq RESTART WITH 649328;
SELECT setval('ehis.citymaster_seq', 649328);
SELECT setval('ehis.citymaster_seq', 649328);
