Dialect differences
PostgreSQL is a database server and XML is a file format, so the gap is wider than a dialect difference - the rows below are where values and structure stop lining up.
| Property | in PostgreSQL | in XML |
|---|---|---|
| port | 5432 | — |
| identifiers | "double quotes" | Attribute values in quotes; entities (& < >) for ... |
| row limit | LIMIT n | — |
| dates | timestamp, timestamptz, date, time | Text (xs:date / xs:dateTime when an XSD is in play) |
| long text | TEXT | — |
| binary | BYTEA | base64Binary / hexBinary inside text |
| separator | — | Tags, not delimiters |
| encoding | — | Declared in the XML declaration |
| typing | — | None in the markup itself |
| shape | Tables of rows and columns | Arbitrary tree |
| ceiling | — | Whole document is usually parsed into memory |
