This section describes functions and operators for examining and manipulating values of type bytea.
SQL defines some string functions with a special syntax where certain key words rather than commas are used to separate the arguments. Details are in Table 9-9. Some functions are also implemented using the regular syntax for function invocation. (See Table 9-10.)
Table 9-9. SQL Binary String Functions and Operators
Additional binary string manipulation functions are available and are listed in Table 9-10. Some of them are used internally to implement the SQL-standard string functions listed in Table 9-9.
