Dialect differences

PostgreSQL is a database server and TXT 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 TXT
port	5432	—
identifiers	"double quotes"	None by convention
row limit	LIMIT n	—
dates	timestamp, timestamptz, date, time	Whatever the writer produced; no convention is guaranteed
long text	TEXT	—
binary	BYTEA	Not supported
separator	—	Whatever was chosen - often fixed column widths
encoding	—	No declaration - UTF-8 works only with a BOM
typing	—	None - every field is text
shape	Tables of rows and columns	Free form; a parser has to be told the layout
ceiling	—	No formal limit

Command line

Side	Command
PostgreSQL	pg_dump or COPY ... TO
