The logic for converting the shell-glob-like syntax supported by utilities like psql and pg_dump to regular expression is extracted into a new function patternToSQLRegex. The existing function processSQLNamePattern now uses this function as a subroutine. patternToSQLRegex is a little more general than what is required by processSQLNamePattern. That function is only interested in patterns that can have up to 2 parts, a schema and a relation; but patternToSQLRegex can limit the maximum number of parts to between 1 and 3, so that patterns can look like either "database.schema.relation", "schema.relation", or "relation" depending on how it's invoked and what the user specifies. processSQLNamePattern only passes two buffers, so works exactly the same as before, always interpreting the pattern as either a "schema.relation" pattern or a "relation" pattern. But, future callers can use this function in other ways. Mark Dilger, reviewed by me. The larger patch series of which this is a part has also had review from Peter Geoghegan, Andres Freund, Álvaro Herrera, Michael Paquier, and Amul Sul, but I don't know whether any of them have reviewed this bit specifically.

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.
