When specified, WITH NO DATA does not insert any data into the relation created, so skip checking for the insert permissions. With WITH DATA or WITH NO DATA, it is always required for the user to have CREATE privileges on the schema targeted for the relation. Note that plain CREATE TABLE AS or CREATE MATERIALIZED VIEW queries have begun to work accidentally without INSERT privilege checks as of 874fe3ae, while using EXECUTE or EXPLAIN ANALYZE would fail with the ACL check, so this makes the behavior for all the command flavors consistent with each other. This is arguably a bug fix, but there have been no complaints about the current behavior either so stable branches are not changed. While on it, document properly the privileges requirements for each commands with more tests for all the scenarios possible, and avoid a useless bulk-insert allocation when using WITH NO DATA.

This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions.
