+title: 'How to fix pg_restore "input file appears to be a text format dump. please use psql"'
+---
+
+This error occurs because you're trying to use `pg_restore` on a plain text SQL dump file, but `pg_restore` only works with binary or directory format dumps.
+
+### Option 1: Use psql instead
+
+```bash
+psql -U username -d database_name -f dump_file.sql
+```
+
+### Option 2: Check if your dump is compressed
+
+If your file has a .gz extension:
+
+```bash
+gunzip -c dump_file.sql.gz | psql -U username -d database_name
+```
+
+### Option 3: Create a custom/binary format dump
+
+When creating dumps in the future, use the `-Fc` flag with pg_dump:
+
+```bash
+pg_dump -Fc -d source_database > backup.dump
+```
+
+Then you can use pg_restore with this file:
+
+```bash
+pg_restore -d target_database backup.dump
+```
