Changelog

0.5.0

Support arbitrary expressions in LIMIT and OFFSET clauses, as well as numbers, allowing using parameter placeholders
Add basic support for ON CONFLICT clauses in INSERT INTO statements: specifying which conflicts is not supported yet, but that's okay
Rename queries module into statements, and use that terminology everywhere
Add a new convenience function called from to create SELECT statements by starting from the FROM clause (e.g. from("Things").select(("id", "name")))
Fix a broken link in WithClause documentation

Add Parameters::next_array function returning placeholder as an array, intended to be used with INSERT INTO queries
Rename WithClause::and to and_with for clarity
Disallow passing Select queries directly into Select::from() without aliasing them first because PostgreSQL requires it
Disallow passing raw numbers into INSERT INTO and UPDATE statements, and update examples to emphasise the raw SQL'ness of everything
No more dependency on Itertools, making the library totally dependency-free
No longer allocate strings unnecessarily when we join a bunch of stuff to build SQL

Write real documentation for most things
Remove unnecessary is_empty method from WithClause as the clause should never be empty
Implement IntoIteratorOfSameType and IntoNonZeroArray for additional tuples up to 12
Support f64, i32, i64 and u64 as types convertible into Expression
Remove Select::new constructor, use the select entry function instead

Export BareInsertInto type from postgres::queries module
Rename UpdateWithoutAnyValuesSet into BareUpdate
Support for CTEs (WITH ... clauses) in DELETE FROM, UPDATE and INSERT_INTO queries
Remove Default implementations from DeleteFrom, InsertInto and Update structs because such empty structs are not valid
Implement Clone for all query structs so you can, well, clone them
Mark all query structs as must_use rather than initial builder functions
Relax itertools dependency
