If pattern is specified, only those publications whose names match the pattern are listed. In latex-longtable format, this controls the proportional width of each column containing a left-aligned data type. Lines being skipped are parsed normally to identify queries and backslash commands, but queries are not sent to the server, and backslash commands other than conditionals (\if, \elif, \else, \endif) are ignored. If pattern is specified, only those event triggers whose names match the pattern are listed. Why did the Soviets not shoot down US spy satellites during the Cold War?

Example: Sends the current query buffer to the server, then treats each column of each row of the query's output (if any) as an SQL statement to be executed. Unique abbreviations are allowed. If you omit the host name, psql will connect via a Unix-domain socket to a server on the local host, or via TCP/IP to localhost on machines that don't have Unix-domain sockets. If the value begins with a slash, it is used as the directory for the Unix-domain socket. Defined substitutions are: The full host name (with domain name) of the database server, or [local] if the connection is over a Unix domain socket, or [local:/dir/name], if the Unix domain socket is not at the compiled in default location.

Without a parameter, toggles the display between on and off. Both the system-wide startup file and the user's personal startup file can be made psql-version-specific by appending a dash and the PostgreSQL major or minor release identifier to the file name, for example ~/.psqlrc-15 or ~/.psqlrc-15.2. Specifies that psql should do its work quietly. WHERE name = 'John'). The command history is automatically saved when psql exits and is reloaded when psql starts up. They can be changed or unset.

Lists text search configurations. If the current query buffer is empty, the most recently sent query is re-executed instead. which is translated to ., and $ which is matched literally. option indicates which option is to be set. In prompt 2 %R is replaced by a character that depends on why psql expects more input: - if the command simply wasn't terminated yet, but * if there is an unfinished /* */ comment, a single quote if there is an unfinished quoted string, a double quote if there is an unfinished quoted identifier, a dollar sign if there is an unfinished dollar-quoted string, or ( if there is an unmatched left parenthesis. If the form \dx+ is used, all the objects belonging to each matching extension are listed. PostgreSQL error reporting follows a style guide aimed at providing the database administrator with the information required to efficiently troubleshoot issues. (See also \errverbose, for use when you want a verbose version of the error you just got.). The autocommit-on mode is PostgreSQL's traditional behavior, but autocommit-off is closer to the SQL spec. To quote the value as an SQL identifier, write a colon followed by the variable name in double quotes. A backslash preceding any other character within single-quoted text quotes that single character, whatever it is. Note that you probably don't want to specify border here, as that is already taken care of by \pset border. The output column identified by colV becomes a vertical header and the output column identified by colH becomes a horizontal header. Lists database roles. The port number at which the database server is listening. Alternative location for the command history file. If a filename or |command argument is given, the query's output is written to the named file or piped to the given shell command, instead of displaying it as usual. This option can be repeated and combined in any order with the -f option. PTIJ Should we be afraid of Artificial Intelligence?

The latex and latex-longtable formats additionally allow a value of 3 to add dividing lines between data rows. That may or may not terminate the script; if it does not, all database-accessing commands will fail until another \connect command is successfully executed. Here, you can just move the conditions from the WHERE clause to the ON clause of the first join: Thanks for contributing an answer to Stack Overflow!
