Error with PG_MODULE_MAGIC macro - Mailing list pgsql-admin

Hi List,

We are under up gradation of pgsql 7.4.2 to latest version 8.2.25 on Solaris-9. While compiling the source, we found some error with encryption file. As per the pgsql admin team suggestions, we included the macro of PG_MODULE_MAGIC, in the code while creating the 2 functions. An error was raised saying some extension files are required as below. Pls through some light on us to get ride of this error and provide some suggestions on this.

create function blowfish_encrypt( text,text ) returns text as '/opt/CommerceLink/code/cl_encrypt_rohan/pgsql_clcrypt.so' language 'c';
ERROR:  incompatible library "/opt/CommerceLink/code/cl_encrypt_rohan/pgsql_clcrypt.so": missing magic block
HINT:  Extension libraries are required to use the PG_MODULE_MAGIC macro

{ Necessity : In general we use the function “blowfish()” to encrypt and decrypt the data on the database. To make this function work properly, we need to create these 2 functions (blowfish_encrypt and blowfish_decrypt). In the pgsql 8.2.5 version, we find this error while including the MAGIC block.}
