Centos / php-pgsql

[Patricio Muñoz]

Estimados,

Instale CentOS 4, y juto con ello la ultima version de Postgres (8.0.2), 
donde no tuve problemas, pero al instalar el modulo php-pgsql, 
aparecieron errores de dependencias. He aqui un extracto de los errores 
desplegados:

--> Processing Dependency: postgresql-libs = 8.0.2 for package: 
postgresql-devel
--> Processing Dependency: libpq.so.4 for package: postgresql-python
--> Processing Dependency: libpq.so.4 for package: postgresql
--> Processing Dependency: libpq.so.4 for package: postgresql-server
--> Processing Dependency: libpq.so.4 for package: postgresql-contrib

Error: Missing Dependency: libpq.so.4 is needed by package postgresql-python

Error: Missing Dependency: libpq.so.4 is needed by package postgresql-server
Error: Missing Dependency: libpq.so.4 is needed by package 
postgresql-contrib

Para solucionar el problema, me sugerieron bajar el o los fuentes de las 
aplicaciones que usen Postgres y recompilar el/los paquete(s). Para tal 
efecto baje el archivo php-4.3.9-3.2.src.rpm y relize los siguientes pasos:

1. rpm -Uvh php-4.3.9-3.2.src.rpm
2. rpmbuild -bb /usr/src/redhat/SPECS/php.spec

Esto genero todos los archivos rpm de php:

php-4.3.9-3.2.i386.rpm
php-devel-4.3.9-3.2.i386.rpm
php-domxml-4.3.9-3.2.i386.rpm
php-gd-4.3.9-3.2.i386.rpm
php-imap-4.3.9-3.2.i386.rpm
php-ldap-4.3.9-3.2.i386.rpm
php-mbstring-4.3.9-3.2.i386.rpm
php-mysql-4.3.9-3.2.i386.rpm
php-ncurses-4.3.9-3.2.i386.rpm
php-odbc-4.3.9-3.2.i386.rpm
php-pear-4.3.9-3.2.i386.rpm
php-pgsql-4.3.9-3.2.i386.rpm
php-snmp-4.3.9-3.2.i386.rpm
php-xmlrpc-4.3.9-3.2.i386.rpm

3. rpm -Uvh php-pgsql-4.3.9-3.2.i386.rpm

Hasta aqui todo ok.

4. yum update

[root en kalisto i386]# yum update

Mi pregunta es:

1. Los errores desplegador por yum (por la biblioteca libpq.so.4) 
traeran alguna consecuencia en el futuro ?

Segun lei, la version de Postgres 8.0.2 para rhel-es-4 esta compilada 
con la biblioteca libpq.so.3, y el modulo php-pgsql (por ejemplo) fue 
compilada con la version libpq.so.4.

Estoy en lo correcto ?

saludos
