.pgaw:Help.f.t insert end "INSERT" {bold} "  allows one to insert new rows into a table. One can insert a single row at time or several rows as a result of a query. The columns in the target list may be listed in any order. In every \
column not present in the target list will be inserted the default value, if column has not a declared default value it will be assumed as NULL. If the expression for each column is not of the \
correct data type, automatic type coercion will be attempted.
