i am curious how we can implement the ternary operator with multiple commands in else part. in my case, only the first command in the "else" part is reachable and the rest is ignored.
in both the cases, the
is not reachable always and the code continues without exiting.
please help me how to achieve this with this syntax. It can be easily rewritten using if-else construct. But, I would like to know how we can accomplish this using this syntax.

Firstly, I would like to apologize if this is not the appropriate sub-forum to post about GNU/BSD makefile scripting. Though my code is in C++, because I am focusing on the makefile I thought it would go better in shell scripting. Please correct me if I am wrong.

create_operator_family
CREATE OPERATOR FAMILY(7) PostgreSQL 9.2.7 Documentation CREATE OPERATOR FAMILY(7)NAME
CREATE_OPERATOR_FAMILY - define a new operator family
SYNOPSIS
CREATE OPERATOR FAMILY name USING index_method
DESCRIPTION
CREATE OPERATOR FAMILY creates a new operator family. An operator family defines a collection of related operator classes, and perhaps some
additional operators and support functions that are compatible with these operator classes but not essential for the functioning of any
individual index. (Operators and functions that are essential to indexes should be grouped within the relevant operator class, rather than
being "loose" in the operator family. Typically, single-data-type operators are bound to operator classes, while cross-data-type operators
can be loose in an operator family containing operator classes for both data types.)
The new operator family is initially empty. It should be populated by issuing subsequent CREATE OPERATOR CLASS commands to add contained
operator classes, and optionally ALTER OPERATOR FAMILY commands to add "loose" operators and their corresponding support functions.
If a schema name is given then the operator family is created in the specified schema. Otherwise it is created in the current schema. Two
operator families in the same schema can have the same name only if they are for different index methods.
The user who defines an operator family becomes its owner. Presently, the creating user must be a superuser. (This restriction is made
because an erroneous operator family definition could confuse or even crash the server.)
Refer to Section 35.14, "Interfacing Extensions To Indexes", in the documentation for further information.
PARAMETERS
name
The name of the operator family to be created. The name can be schema-qualified.
index_method
The name of the index method this operator family is for.
COMPATIBILITY
CREATE OPERATOR FAMILY is a PostgreSQL extension. There is no CREATE OPERATOR FAMILY statement in the SQL standard.
