Pager  can  also be set to always, which causes the pager to be always used, or you can set the pager to on which will enable the                      usage of the pager when appropriate, or you can set the pager to off which will disable the pager. On the other hand, set bar foo is a perfectly valid way to copy a variable. You can pick up where you left off, or start over.

Visual editor used by the e command. If there is no pre-               vious connection, the libpq default for the parameters value is used. If the html format is already on, it is switched back to the default aligned text format.

If this parameter contains an sign, it is treated as a conninfo string. Thus to set the output format to latex, you could write -p formatlatex. The default prompts are r for prompts 1 and 2, and for prompt 3.

Gives  syntax  help on the specified sql command. If  this  variable is set to an integer value 0, the results of select queries are fetched and displayed in groups of that many rows, rather than               the default behavior of collecting the entire result set before display. If  the  form  dft  is               used, additional information is shown about each template, including the underlying function names.

This means that file accessibility               and privileges are those of the local user, not the server, and no sql superuser privileges are required. The  various  d commands accept a pattern parameter to specify the object name(s) to be displayed. If the form dfp is used, a               full description of each parser is shown, including the underlying functions and the list of recognized token types.

Write all query output into file filename, in addition to the normal output destination. In this intermediate-level course, kevin skoglund introduces object-oriented programming (oop) principles for php. Therefore only a limited amount of memory is used, regardless of the  size               of  the result set. This command is kept               for backwards compatibility. First load the file into a variable and then proceed as above        one  problem with this approach is that myfile.

This command is identical to echo except that the output will be written to the query output channel, as set by o. The syntax for this is again        would  then  query  the table mytable. Your database administrator        when the defaults arent quite right, you can save yourself some typing by setting the environment variables pgdatabase, pghost, pgport andor  pguser  to        appropriate  values. This is different from the behavior when the same string is fed to psqls standard               specifies the name of the database to connect to. Thus to set the output format to latex, you could write -p formatlatex, In html mode, this will translate directly into the border attribute, in the others only values 0 (no border).

    To ensure        maximum compatibility in the future, avoid using such variable names for your own purposes. Thus to set the output format to latex, you could write -p formatlatex.

    Lists all data types or only those that match pattern. If no arguments  are  speci-               query  results  includes  all  tables, command responses, and notices obtained from the database server, as well as output of various backslash               commands that query the database (such as d), but not error messages. In normal operation, psql provides a prompt with the name of the database to which psql is currently connected, followed by the string. This  option  is  never essential, since psql will automatically prompt for a password if the server demands password authentication. This way you can study the postgresql internals               and provide similar functionality in your own programs.

    . Should you need to include an actual double quote character in a        pattern, write it as a pair of double quotes within a double-quote sequence again this is in accord with the rules for sql quoted identifiers. If  the  second argument is not provided then we will toggle between tuples only and full display. List the names, owners, and character set encodings of all the databases in the server. Saves future query results to the file filename or pipes future results into a separate unix shell to execute command. The value of the selected prompt variable is printed literally, except where a percent sign () is encountered. When no dot appears, then the pattern matches only objects        that are visible in the current schema search path. This is equivalent to the t command. If pattern is specified, only tables, views               the grant grant(7) and revoke revoke(7) commands are used to set access privileges. The  default  user  name  is        your  unix  user name, as is the default database name.

Thus you can construct interesting references such               as set foo something and get soft links or variable variables of perl or php fame, respectively. This command is equivalent to pset title title. Within a pattern, matches any sequence of characters (including no characters) and ? Matches any single character.

    This is equivalent to specifying dbname as the first non-option argument on the command line. The onerrorrollback-on mode works by issuing an implicit savepoint for you,  just  before  each               command that is in a transaction block, and rolls back to the savepoint on error Buy Unix Variable Assignment at a discount

    Readline library for convenient line editing and retrieval. Your database administrator        when the defaults arent quite right, you can save yourself some typing by setting the environment variables pgdatabase, pghost, pgport andor  pguser  to        appropriate  values. If  an  argument is found that does not belong to any option it will be interpreted as the database name (or the user name, if the        database name is already given). If pattern is specified, only functions whose names match the pattern are               shown. Unix commands use the same escape char-        since colons can legally appear in sql commands, the following rule applies the character sequence name is not changed unless name is  the  name        of  a variable that is currently set Sale Unix Variable Assignment
