Dialect differences
TSV is a file format and Redshift is a database server, so the target has to be told the types the file never carried - the rows below are where the two sides diverge.
| Property | in TSV | in Redshift |
|---|---|---|
| port | — | 5439 |
| identifiers | Rarely used, which is exactly why tabs in data break it | "double quotes" |
| row limit | — | LIMIT n |
| dates | Conventional text: 2026-09-18 or 2026-09-18 14:30:00 | timestamp, date |
| long text | — | VARCHAR(MAX) |
| binary | Not supported - must be encoded | — |
| separator | Tab | — |
| encoding | No declaration - UTF-8 works only with a BOM | — |
| typing | None - every field is text | — |
| shape | Flat table, optional header row | Tables of rows and columns |
| ceiling | No formal limit | — |
Command line
| Side | Command |
