Dialect differences

XML is a file format and PostgreSQL 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.

port	`—`	`5432`
identifiers	`Attribute values in quotes; entities (& < >) for ...`	`"double quotes"`
row limit	`—`	`LIMIT n`
dates	`Text (xs:date / xs:dateTime when an XSD is in play)`	`timestamp, timestamptz, date, time`
long text	`—`	`TEXT`
binary	`base64Binary / hexBinary inside text`	`BYTEA`
