postgresql: how to fix a syntax error when importing a CSV file

I am very new in this.

I am trying to import a CSV file into a table that I created.

I used this command before when I used a & # 39 ;; & # 39; delimiter But now the file has a tab delimiter, so I changed my command

COPY Opendata_appraisal_data_usa FROM & # 39; /Users/admin/opendata_appraisal_usa_texas_brown_2018_geocodio_42516d95fdd0be1e4d4e90625689fb17b4e478a3.csv' with csv headerix & # 39;

but now I'm getting a syntax error. Any ideas about what could go wrong?
